Our neighbors have been putting on a plow and picker day in the fall the last couple of years. They also have a sheller or two running that day. Many neighbors bring equipment and alot of others stop by to try their hand at some of the activities. I took a few pictures last fall, and I will try to attach a link to a slideshow of the photos. The interest in tractors has been strong for quite a while, and now people are looking for things to use them for.

I think pickers, plows and wagons and any tillage items are gaining collector interest.
