i'm older and a little slower, but would have continued to ride my motorcycle if we hadn't needed the money for gas for our currently stalled trip to the east coast. loved that bike; miss it. love the RV, but haven't driven this one (class a); only the previous class c. i've been helping my d-i-l clear land here in indiana. physically, i feel i could drive it if i had to (at 71). i have no doubt DH (72) could continue to drive it for some time yet--thank heaven--he's in good physical shape. it's not the number, as my m/c buddy used to tell me when i wondered the same thing; it's the ability.
