Replying to BMX - NW Washington

Anyone in the Washington forum know of sick skateparks that allow bikes, or even local trails that are sweet to ride (within a couple of hours of Seattle)???

My boyfriend and I are heading to Seattle next week to visit my sister and would love to check out the Washington BMX scene. We will have our bikes, and if there are any trails are also definitely willing to help dig / help out in any way we can while visiting.

If none of you guys ride BMX do you know anyone in the area who does?

Thanks a million!!!!
