After cleaning the bike good today, got to the wheels, and found a big, double headed nail in the back tire. Looks like it's been there for awhile, but I use this bike for transportation to and from work, which is 30 miles away. I'm thinking this nail has been there for some time, but I'm concerned about riding the 20 miles on the Los Angeles freeways tomorrow. I have a HD dealer about a mile from work. If I take side streets, it's going to take me an hour and a half, instead of 45 minutes.... but I think I will, just to be safe. What would you do? My other option is calling a tow truck tomorrow when I get home, and haul it up to a dealer near my house. Problem with that is, I'll have to drive the car two days.... I hate that !!!!
