Flat repair is easier now than when my Dad showed me how back when we were dodging dinosaur droppings on the roads.

Not having my Dad on hand, however, I suggest you click on the yellow TE logo at the top of the page, -> community -> how-to guides. Print them out, go out into the back yard and practice. It's best if nobody is at home when you do this, they'll try to "help." (As though that will help later.)

Go for it, girl, what's the worst that can happen?
