NOTE: If you MTB in Portland's Forest Park, Powell Butte or Tillamook State Forest, then join PUMP. They make it possible for you to bike for free in those areas.  If you MTB in Central Oregon and find a trail that has been cleared, guess what?  All those trails are maintained and made possible by COTA. Join both groups, they need your support. Together it's a modest $35.00 per year. What a cheap "fun ticket"!  You can download applications from their respective sites above.  If we don't support them, the trails will close!
