I'm interested too, it's been since last New Year's that I was there. My only hesitation comes in remembering the "traffic jam" mess from so many people being out there at the same time last year. Not that I ain't feelin the love and all just that looking at the same spare tire and brake light for 45 minutes while moving less than 100 yards gets old!
We'll see what the total # of attendees is as the date gets closer, Hardrock is fun with a small to medium sized group but if you cram too many in there it becomes more waiting than wheeling. That aside, I haven't been there since 2007 so I'd be down for going again
