I can't vote either. I have been to every national since Rhinebeck in 99 and have enjoyed them all. I too am a loner (usually.) I go because I love to see the bikes, the vendors, and to enjoy a few beers while seeing some great bands (last year's thursday show at spokane was outstanding!) I am looking forward to seeing George T. this year. I am not thrilled with Lima, but plan to travel better roads the following week. The rallys give me a destination and an excuse to ride, sometimes a long way (NY, WA, OR.) Last year I rode alone, but volunteered for registration on Saturday and attended ERC on Thursday. Met lots of nice people.
I'll be planning for next year as soon as I return from Lima. I put in for vacation a year ahead and book some rooms along the way.
