March 9th, 2008, 35th Annual Rocky Manginelli Memorial Swap Meet. State Fair Grounds, Lincoln, NE. Cash or food donation to attend. Check Hemmings for more information.
This is a great swap meet and you will want to come early(7:00 am) if you are buying. It is usually mostly over by early afternoon. A lot of folks start packing up to leave around 2:00 pm depending on the weather which is usually crappy.
I don't know what vender spaces cost, but I think it is about $20 for an outside spot. This is a great place to look for all kinds of car and truck parts and is just a heck of a lot of fun. I don't have anything to do with this swap meet other than I have attended most years.
