I'm 30 minutes away, so I'll go for a couple of the days. Partly because my friends and I always look forward to it, and then also because I need to get some items for my new Fat Bob.
Been once, for the 50th. Would never go again. To crowded. To many lines to get in anything. More into touring and the path less taken at this point in my life. And for some reason I don't play well with most others.
My father who is 75 goes every year period. He loves it and has friends who live there or very nearby. He still rides, just not as far.
