Guns N Roses comes into my mind every time Im going down a technical hilll so I start singing it, Welcome to the Jungle, Sweet child of mine, knocking on heavens door and all the rest. But going up the hills, its more like, ah #%$@ theres a root the size of a $@%# semi, if I make it over without crashing I'm like Holy , then if I crash I'm like Holy ! Then when you get behind a slow rider it all changes, you start saying to yourself you know, get the h out of my way, or come on grandma, all kinds of weird stuff, kinda stuff you wouldn't say to your mother. Also for some reason when Im riding through a flat boring trail to get to the rest of the trails, I'll started singing, She thinks my Tractors' Sexy, dunno where that comes from. It relaxes your mind and helps you ride better IMO, I also believe listening to your favorite rock or whatever really loud on your expensive system to the trails gets you pumped up and ready to ride!
