I headed out to the nearest bike shop, a 3 mile roundtrip walk, to get replacement parts. It wasn't cheap, either because it wasn't just the inner tubing that burst but the external tire, too. It's not cheap to get a replacement for a very specific kind of racing tire.
And to top it all off the walk to the bike shop goes through what could courteusly described as low-income housing. I got rushed by three large dogs (hooray for fences), and almost got peed on by another through a fence if I hadn't noticed the raised leg and dodged away.
Fun day, especially when you've only had 3 hours of sleep because you like video games too much.
