My commute home this afternoon ended up being via bus, with my bike in the bike rack on the front of the bus. I was all changed and geared up to go home and as I was rolling my bike out of my office I noticed a lot of rolling resistance. I look down and my front tire is completely out of air.

I limped the bike about 1/3 to 1/2 of a mile to the transit center, missing the bus by about 1 minute. Normally this would be fine in May, but it was no fun waiting the 30 minutes for the next bus in 45*F and a 15 MPH wind, it felt like March today. I didn't get home before my LBS closed, so I ran the wheel over to Dick's Sporting Goods and had the tube replaced. I think I overinflated my front tube this morning and may have blew the tube out. Oh well, lesson learned!
