If you remember, I mentioned that I had my left tibia develop a stress crack while Kathy and I were hiking the Great Allegheny Passage. I saw the doctor again yesterday and he feels that I'm fully healed and am cleared for hiking on trails. In fact after some excercises he had me do he thinks my legs are stronger than most 70+ year old men. I'll try our local county park soon and I see an overnighter in NY's Harriman State Park in the near future.
