The Backcountry Bicycle Trails Club (BBTC) is an International Mountain Bicycling Association (IMBA) affiliated mountain biking organization located in Seattle, Washington, USA. This mailing list is intended for discussion about any and all topics relevant to mountain bikes, mostly focused on Washington State. This list is NOT for commercial solicitations or political discussions not related to mountain biking. You're welcome to use the list to propose and organize rides, though usually that's done using the BBTC Ride Calendar at http://bbtc.org/recreation/. The BBTC also offers Basic MTB Skills classes on a regular basis. The list gets 10-15 messages per day on average.
