I would love to be able to burn more shoe leather. But my mail carrying career is coming to an end as i'm being plagued with arthritis and burcitis in the knees and the hip i had replaced. Then to add to the fun, herniated discs and pinched nerves.Sure would of treated my body differentley through the years if I had seen this coming. It sure sucks getting old. Thanks guys. May your season be fulfilling and rewarding....
