I'm 29 and relatively new to snowboarding, went once a few years back and rented gear.
I don't like renting equiptment, so I bought a used board and bindings from a guy who said he only used it twice and then realized snowboarding wasnt for him. Board looks new and still has the inspection sticker on it. Got the board and bindings for 125. Also bought some cheap M3 boots for $50 at Big 5.
Figured I'd save cash by buying the gear as opposed to renting, plus I don't like using other people's boots.
Live in SoCal so I'll be hitting up local places and maybe Mammoth again (skiied there)
Been reading different threads to learn more about boarding.
