If you have already established a cache in a Washington State Park but have not informed the park manager or have written permission to establish a cache PLEASE promptly take steps to get that permission per the new directive as soon as possible.
Well, my Potlatch cache is certainly one of these, because it's in Potlatch state park, I hid it on March 17, 2002, and I never obtained written permission to play the game in the park.
I checked out the new policy (effective July 6), and I certainly don't want to take the time to meet with the park ranger, obtain a permit for it every year, and visit the cache every 90 days. I also don't like having to indemnify the state against claims arising from the geocache's existence. It's a lot easier just to archive it, and let someone else who wants to jump through the hoops place one in the park.
