Laconia, NH. Bike week. Been going for years. After you get tired of looking at T shirts and cheap leather, the area offers a whole bunch of great riding on winding roads thru the mountains, lots of lakes, and not much traffic once you get out of the immediate area.
The local campground can be fun at night, watching all the antics going on, and such. Last year had a bet with one of my buddies how many times this one guy could get drunk and drop his dresser in the field we were camping in for the week. I lost by the way, and stopped counting after six times.
