I'll be glad to join you! No real heart problems (any more) but a bit overweight and lots of nagging injuries from running track and cross country in colelge at OU. Those 100+ mile weeks are really hurting me 20 years later. I can't even ride a bike, so don't know what I would do marching, advancing, retreating- all in well fitted, comfortable shoes!
I'll stick with my computers and walking in cemeteries....unless the mint julips are fresh!
