Several days ago I was driving home, and in the passenger-side floor of my truck I had a pedal hooked up to a woodblock, since I'm trying to get into some of that left foot clave independence stuff. I got an idea, which is probably pretty dumb, but anyway... I slid my seat back and set the woodblock and pedal underneath my left foot, kind of next to the brake, and I turned up the radio and practiced drumming on the steering wheel (with sticks of course!) while keeping the left foot clave going. That's bad enough, but then a Def Leppard song came on, and I realized my cowbell was in the passenger seat, too, so I of course had to play it as well. It goes without saying that driving like that is kind of hard, so don't get yourself killed if you decide to try it yourself! I must have looked pretty strange...
