Oldest g'daughter volunteered me to drive a tractor selling rides to people at a county fair. She is in 4-H. Drove a Kubota L 5030, I think, which was a sweet little tractor, 4 wd, better power steering than on some cars. Automatic transmission. The lady who drove it before me hadn't driven a tractor before and the one who came after didn't either, but both did fine, slowly. Anyway, wife, daughter, and I were leaving to transfer something from our car to hers and we stopped by a Woodmizer sawmill demo. They were loading a fairly large stack on green lumber on a double axle trailer and stacking the lumber at the back of the trailer, not centered a little ahead of the axles. I told my daughter to look at the load so she would know how NOT to load a trailer and explained the problems that poor loading would cause. To be fair, the trailer was hitched to one in front of of it and both were hitched to a nice JD B, and maybe they were just going to move the lumber to the drive way to transfer it to a truck, but they still could have problems. They were still sawing and loading when I left.
On the same line, I saw a patrol car had a pick up truck with two empty trailers hitched in tandem on my trip to St Louis, guess that's illegal too.
