Today's commute was great. Perfect tailwind for much of the way in. Then, I looked down and noticed something stuck to my front tire. I tried to wipe it off while I was riding, and it wouldn't come off. I stopped and discovered it was a thumb tack. I started to pull it out, and it started hissing, so I pushed it back in. To my surprise, it stopped hissing and didn't go flat. I continued to ride on it, to try to make it to work where there's a floor pump, so I wouldn't need to use up my CO2 cartridge (I'm a cheapo ). Well, I made it about 4 more miles, then all at once, it went flat. I was still 4 miles from work, so I ended up using my beloved CO2 .

On the evening ride, I stopped at the lbs to replace the cartridge. Back on my bike a few miles later, I passed an accident at an intersection that I probably would have been at, had I not stopped at the shop. Then, after I got to my car, another really bad accident on the bridge I drive over. When I think about "what could have been" if I had been a few minutes earlier....

Had I not flatted this morning, I may have been involved in either of those. Just goes to show, you never know when something that seems bad is actually good.
