Nanci, I can NEVER find the hole! Maybe it's old eyes.

I take two tubes with me. I've had flats where the replacement tube had a defect (usually around the valve).

You've received some GREAT advice about sitting in your living room & practicing. The rear wheel can be difficult if you have never done it before.

I'm surprised nobody asked to help! What is this world coming to? I always slow down and call out "Got everything you need?" If it is a women who appears to be struggling, I'll stop. Another good reason to carry two tubes - I've been able to give away a tube to hapless cyclists.

Karma is a good thing!
