Call Barb and tell her when you are going to be in the area so that she can order what you want and have them on hand when you arrive. Even if you have to pre-pay for the tires it saves a lot of hassle and the slight extra expense is not that much especially when you amortize it over 5 or 6 thousand miles of use. Besides it is a nice gesture to leave some cash at local businesses so that they might be around to help out if other real problems arise. My $.02 worth. Enjoy your trip! ps: Are you going to the Mayday Melee?
