What's Your Favorite Summer Motorsport?

We're starting to enter the gravy months of racing when nearly every series has something going on every weekend. Whether you're a participant, a spectator or you just enjoy the track from your TiVo, it is a great time to be a racing fan. But with this embarrassment of octane-fueled riches, what occupies your time? Do you autocross? Do you Baja? Do you Le Mans or do you LeMons? Are you like Brian Williams, obsessed with the dirty oval or are you more refined, like Max Mosley?

Do you like to watch? Do you like to play? Better from home or better from the side of the road? What makes you feel cool when it starts to feel hot?
