When driving alone, what do you do?  Sing along to the radio?  Think about your day?  Something else?

I listen to podcasts. I have a dock for my iPod in my car (actually, the pic shows my old one, which died about this time last year. I got a new 80Gb one from Lorna & Mum for my birthday).

I spend just under two hours in the car each weekday, so it gives me plenty of time to catch up on the latest podcasts on a while range of subjects.

Sure, sometimes I listen to music, especially if I'm pretty tired, but I do like the intellectual stimulation of talk podcasts when I'm driving the same old route for the umpteenth time.
