The Barrel Train

Inquiring minds were asking, "What the hell is your child daring to ride on at the pumpkin patch?" Well, all, it's a line of old barrels on wheels strung together and pulled by a small tractor. Here is a subsection of the "train":

Just because I'm a jackass, and in case you are completely concrete jungle raised and you've never ever been in the country, here is a tractor:

And I think since the barrels are more than likely old chemical barrels (from a certain company with whom I may or may not have been employed), those of you who don't like modern farming will probably give me this:

Spoil sports. Jeez. It's not like they aren't CLEAN! And before any anti-chem panties get in MAJOR wads - the farm chem once residing in these barrels is inert to humans. Although, the barrels can be purchased for farmers to mix their own chem, so it's entirely possible that these were purchased just to make the train and never held any chem at all. That will help me avoid any possible egging of my home or car, right?
