Bellingham BMX :: Bellingham, WA
You can grab some tools and jump in a crew, ride your bike around the loop (avoiding the work crews, of course), take in some refreshments, & chat with your friends.
Come and go as you please (gate must be opened & shut each time). Bring clothing adequate for working with hand tools in the dirt plus whatever you prefer to ride in.
Bellingham BMX is at 5022 Guide Meridian (map) just north of Kelly Road and south of Smith Road. Look for a long chain link fence and white buildings painted with orange trim. It is across the road from a "Gifts & Things" store with flags & banners out front.
Here are some alternate bike commute routes to the track via backroads & trails.
