I didn't start backpacking untill I was 49.
It truly amazed me when I ran into these older kids in their 60's and 70's. After trying out backpacking, I know that this was something I wanted to do when I retired. Its been 3 great years of backpacking and I am looking forward to the time I can go out for more then 6 days at a time or more then 2 weeks a year.
