Very good lesson! Thanks Grog!

One thing I do know how to do is change my tire. My husband made sure I knew how and knew how to do it CORRECTLY! I always look for what may have caused the flat. For example the other day my daughter and I went on a bike ride and not 5 minutes into our ride she had a flat. I removed her wheel, deflated the remaining air, pulled the old tube out and then checked with my fingers for something sharp and sure enough I found it. A thorn from a blackberry bush had worked it's way through her tire. I removed it, did another check and then placed her new tube inside her tire. Before I inflated her new tube I quickly went around the circumference of the tire checking for any part of the tube that may be "pinched" between the tube and the rim. Satisfied, I inflated her tire and we enjoyed a wonderful 30 mile ride without any further tire trouble.

I hope your ears are ok Grog! Some people just think fast is better. It's only better if you do it correctly! So what if it takes me 10 minutes to change my tire? I feel a lot safer and better knowing that I did a good job then a rushed job. Like you mentioned I wouldn't want a flat going down a steep downhill!
