I just attended this event yesterday. Missed it last year. This was the third time I've been to this one.
This is held every year in Somerset, VA.
I didn't get any pics of the smaller lawn and garden tractors, but there are always lots of them around. I didn't find this forum until last night, after I got back from the show - otherwise, I would have spent more time taking some pics of the smaller machines.
But here are a couple pics to give you a general flavor of the event.
