I used to collect little metal spoons from everywhere I traveled as a kid. I think I still have them all in a box somewhere. Sports cards was the big thing for me as a kid, I know I have every bit of 700,000 card in totes still, if not more. It just sucks that the market on those things tanked out, I was sitting on a fortune as a kid haha.
My wagon obsession is getting a little out of control, although some of them I have purchased with plans of modifying/selling to family and friends. Others I am just hoarding as you don't see them very often. I don't like collecting just run of the mill Radio Flyers, I look for things like Radio Jets, Murrays, AMF, ect... Just the random wagons that were produced through out the years.
