I had to chime in because I just got home from a ride where I had my first flat in years - I'm just getting back into riding. Oddly, I decided to stop and check my tires for no particular reason and found that the back tire was a little low and saw the offending thorn sticking out of it. I had a patch kit and remembered how to fix it...except that I apparently didn't wait long enough for the vulcanizing glue to dry before applying the patch because as soon as I got the tire put back together and pumped up - it started leaking again! Oh well, practice makes perfect, right.

I am interested in learning how to put the tire back on the rim without using the tools because I've pinched tubes before that way. I'm wondering if I don't have the hand strength to do it or if there is a technique I need to learn. I am signed up for a class coming up shortly.

I second (or third, or fourth) the practice in your living room before it happens to you approach.

I must say, there were several friendly cyclists who asked if I needed any help and if I had everything I need. Interestingly, some even said they didn't have anything to change a flat but offered their cell phone if I needed it.
