Dang, this is frustrating. After doing a lot of hiking in Colorado last week, I was really looking forward to riding my bike.
When I pulled it out, the back tire was flat. I filled it up and took off, but after the first mile it was flat once again. Luckily, I was able to get back to the house without any trouble.
This photo by JR Goleno pretty much sums up my feelings on the matter.
