I'm part of a group from Growlers Gulch Racing that is building a bike park in Castle Rock, Washington (Exit 49 on Interstate 5).

Tweaking will go on for some time, but we were able to complete both a beginner and advanced pump track this summer and feel great about that.

I'll start by saying that in this case I realize that bigger doesn't necessarily mean better, but here's what I'm wondering - the advanced track is 320 feet long, with 36 rollers and 13 berms. Somebody told me that would make it one of the bigger pump tracks in the Northwest. However, I don't want to make that statement until I get some confirmation.

Any relevant feedback you can provide would be appreciated.
