I want to ski again!

Go hiking more. Mainly keep up w/my kids and do fun things.
Big goal is to run this 1/2 marathon that we have in my area. It's up hill part way. When my dentist heard I had my surgery he planted the idea in my mind and said he'd run it with me - lol! That idea seems almost impossible, but it would be so cool if my body could do something like that!
