I'm pretty sure it wasn't a pinch flat. After I put the tire on the tube, I checked the wheel to make sure that the tube was all in the tire, but I will check tonight. It wasn't 100% flat, but it went flat enough that I'm pretty sure it was a flat.

At, 1st I didin't know what to do. It took me a second to remember how to change a flat on the road. Glad I still carry all the tools I need.
