Fix-it shop

On Monday dad blew a tire out. So we had to make a trip to the bike repair shop set up in town. Several days later I blew my tire out and had to make a trip to the fix it shop. Then on Friday Dad asked if I felt that "lump, lump, lump" in the road. I said "No!" He said, "Well, we better pull over." Turns out his brand new tires were bulging and he had to replace them again!!
