There is a place near where I work that always has the best price and selection. I can easily buy the tire there, but I wanted to "buy local" and let the local guy make a dollar or two on it. I had a bike shop here in the 70's, and too many people would buy elsewhere, looking for a deal, when I could have made them the same deal locally.
Besides, it is just too damn hot right now for me to want to do all the work! I'll bring the wheel in off the bike, I want to inspect the bearings and brakes personally. Bought the Dunlop 491 Elite II, a high mileage touring tire.
