I LOVE old time radio shows! Like GLC, I'm podcast-deficient, but I do have a satellite radio and listen to Gunsmoke and Dragnet from the 50s. It's great fun.

As for training, IF I can figure out how the whole podcasting thing works (my mother gets it, but I somehow can't), I'll check out the running one, as I'm toying with the idea of doing a triathlon by the time I'm 45 (my original plan was by the time I'm 30, but I was in grad school, and then by 40 but I was getting divorced, yadda yadda yadda).
