Any good 15+ wind should keep you up on the right slope..

You are looking for a hill with a good rise and long straight face that will force the wind up and not around the hill.

Links to good flying sites in Washington.

Check out the RCG slope forum.. Lots of WA slope fliers there.

If you get to the SE side of the state check out Eagle and Kiona in the Tri-Cities.. Some of the best slopes on the west coast.
40-50pmh winds are not uncommon on Eagle.. bring ballast!
