I drove a semi sometimes for a couple years for my family farm. Didn't drive a whole lot, and pretty much all on back dirt roads and in lots/fields, to get some experience before possibly getting a CDL. Never ended up getting the CDL because I moved and changed jobs. I was around and learned from skilled drivers (my dad for one), so I know a little bit, but I'm certainly no expert. That being said:

Backing up a vehicle with a trailer is quite difficult because compared to a normal vehicle with no trailer, all your intuition is wrong and little mistakes get amplified quickly.

Backing up a car and want your tail end to go right? Turn the wheel right. Want the same thing to happen in a semi with a trailer? First turn the wheel left while you back up, which will push the tail end of your tractor left, causing a reaction like pressing on a lever that pushes the tail end of the trailer right. But don't overdo it, because that same lever-type action causes more movement the further you get away from the fulcrum point, so a tiny move there can result in a BIG swing.

Complicating that, you have no central rear view mirror. Side mirrors work, but distance can be obscured by the huge trailer very quickly.

Basically, backing up is one of the most daunting things about learning to drive a truck, particularly for people new to it. The "pull ups" he mentioned are the best way to overcome that. Pulling forward a short/medium distance gets the tractor and trailer back into alignment, so that straight back should result in the trailer going straight back. From that point, you can try to make small corrections. If it starts to swing a lot, pull up again and straighten out, lather rinse repeat.


The guy in the video does a good job (way better than I could do), but he seems to think he's the shit. I don't think you earn real trucking community bragging rights until you can reverse double trailers, or even triples if you want to be worshiped as a god.

Here's a video with doubles:


One of the full-timers on my family farm was quite good with doubles. Not "obstacle course" good, but I saw him reverse a slow circle around a grain bin. And he liked to tell stories about a some semi-mythical whiz guy that could reverse triples around a corner, etc.

My family owns and operates a farm, wheat and corn, in Kansas. We use Roundup herbicides sometimes.

Specifically, there is a GMO variant of field corn called "Roundup Ready" where the corn is genetically resistant to the herbicide. Plant a field of that corn, then after it emerges but well before harvesting (obviously) spray it with Roundup, diluted to an appropriate level. All of the pest plants in the field die. The corn looks a little wilted / harried for a few days after spraying, but bounces back and grows out just fine.

We use that specific kind (Roundup Ready) about 1 year out of every 4 or 5, only when pest plants are starting to become an issue. They'd love to sell it to farmers every year, but most only rotate it in when necessary, just like us, and use a small amount of normal seed (not GMO, just some of the normal corn we harvest) held in reserve from previous year(s) in the other years.

Before Roundup (and other major herbicides and pesticides), pest plants could be a major problem. From what my family says, corn can cross-pollinate or do some kind of hybridization with other crops like milo or sorghum or something, which results in a sterile cane-stalk plant like corn that produces no actual grain. Back 20+ years ago, that was a fairly major problem ... but it is very easily controlled nowadays with herbicides, and Roundup in particular.

Pure, concentrated Roundup is pretty nasty stuff. Then again, farmers still use or have used a lot of much nastier stuff during normal farm operations, like Malathion being sprinkled into grain bins to kill off insects and other small pests. I wouldn't want to chug down a glass full of any of that crap, BUT on the other hand I think we're way better as the human race off WITH all these things being used to control what can be or have been significantly damaging pests than how things would be WITHOUT them. Not to mention that all of these things are used in very very trace amounts compared to the actual amount of food produced itself, and usually a *really* long time before it becomes food. I think you'd be pretty hard pressed to detect any of them in the parts-per-multi-multi-billion scale by them time we eat them.


...That being said, the dude walked right in to this one. If his message was "this stuff is 100% safe and beneficial if used properly", I'd actually 100% agree with him. But when he's trying to oversell it by saying that it is perfectly safe to drink a glass of it ... of course somebody is going to call his bluff. Duh.
