Cribbage board (1)
Decks of Cards (2)
band CD's (x)
spare hat (you never know!)
digital recorder
spare jacket
hockey sticks (4) [once you get into a serious hockey stick collection, the tendency is to push it as far as possible]

oh and my coup d'grace: I have a window-cling of Manny Ramirez's head attached to my left rear window.

I feel like such a non-offroad guy right now. Help me someone!
