yes, i went to greys lake last year...good size show, however, i think it was geared more toward the grass drags.
they did have a good sized swap area, but i didnt see all 4 manuf at the show. i know yamaha and skidoo were there w/ test rides.
i would have ended up going this year, but this weekend U of M kicks off the confrence opener against wisconsin at home. let us know how it was, and take some pics too
