Hey Pete...sorry to hear about your chair. I too lost some items at the night drags. Flashlight someone needed for a headlight and a Tupperware bowl with homemade salsa in it.
I just went down to the dealership I bought quads (2005) and motorcycle (2001) from and they looked them up and gave me 3 stickers. I would think that without proof you paid taxes on the quads, you'll have a hard time getting the stickers.
