couple years ago I young fellow put an add on the craigslist he wanted some one to teach him to work on dozers so It got me thinking if anyone on here has thought about teaching a class on tractors. now I realize there are a lot of different tractors but basically the all work the same. I know there are people on here a lot smarter than I am and the way its going these young people don't know squat about them. I think you could make some good money doing that. if you get 5 people and charge them say 500 bucks apiece for a 30 day course you could do fine. I think this could work for a lot of different items.
