okay, whats the deal? iv heard thet it costs like $35 to ride it, and iv heard from another guy that you just show up and ride. i live in everett, seatac is a ways away, i want to go down there for my first time tommorow (sat), but i dont wanna go down there to find that it will cost me an arm and a leg (that i will prolly break later that day), to ride some hills. is there an official site that has hours, rates, ect? thanks.
