One spring day, I was out JRA on my fixed gear with bolt-on hubs, when boom! the rear tire flatted. No prob, I had my tools! Unfortunately, I had not checked to see what was in my pack...and my mini adjustable wrench rusted shut over the winter. Without the wrench, I was kinda screwed.
So, I started walking toward the nearest town, about three miles out, where I knew there was a bar and would likely be some guys with tools in their trucks. I made it about two miles, when the cavalry showed up - a lovely young couple out on their road bikes. They stopped and immediately offered to help. To make things even worse, my spare tubes were bad...and their spare was bad...and the guy literally rode back to town (the one I was heading to) to get more tubes.
So, that's a shout out to Matt and Heidi! I still hope I didn't ruin their ride, and for the past three years, I've owed them a tube.
