If you think you know a lot about motorcycles and what to take it to a higher plain check out the International Journal of Motorcycle Studies. It's an online journal of people who take motorcycles very seriously. However, this is no egghead journal just for physics and chemistry. In the current issue is an article on "A Matter of Style--Charlie Parker and Jack Kerouac: Between Coolness and Ecstasy" and "Marx and McQueen: Racing against Communism in Fordist America" Bird? McQueen? How cool is that!?
There are book reviews and an article on a German art/motorcycle exhibit. Something for your brain on those cloudy, rainy days when you're stuck inside.
