Here's the freebie rundown that I remember (and this is pretty cruel to those folks who couldn't make it :-):

SonicBlue Polo shirts
SonicBlue Tshirts (I didn't see one of these)
Empeg "first USA owners meet" Tshirts (also has "RioCar" on it)
Rio baseball caps (very nice quality)
a large bag of Rob's knobs

Rio600's for the SQ/IQ tests contest winners (of which there were 5 (3way tie, 2way tie))
A Nike player for the quiz winner (of which there was one, 16pts to 15pts)
