I found a few places to ride like on the mountain loop hwy (pass Granite falls) but would like to know some more places to ride. Next year I plan to buy a used Giant VT ONE so I a XC/all mountain type rider.
check www.bbtc.org (Seattle) or www.stmcc.org (Tacoma), two local clubs that post group rides on their websites. I'm sure there are more, but those two come to mind. Get a guide book, there are at least three that cover the area fairly well, available at your friendly independent bookseller, etc.
