All 50 states
I've been to all 50 states, but not on the bike -- have ridden bikes in 40 states, including Hawaii (on a business trip I rented a Harley for the day and a friend and I toured Oahu -- very nice, but would have been nicer on my Valk). Have also ridden in British Columbia and Alberta -- just beautiful. Doing a several trips this summer but will be adding Washington, Michigan, Alabama, and Arksnsas. A couple of us had planned to go to Alaska this year, but holding off on that. Instead will be doing several two-week trips.
I guess the ones that I will still be missing will be:
Alaska
Georgia
South Carolina
Mississippi
Oaklahoma
Louisana
On second thought, may kill a couple of those this year also.
