I'm biased of course, but Rattlesnake lake is about as central of a location as you can get (easy I-90 access for east or west of the mountains, and less than 2hrs from Olympia or Everett).

It doesn't have a big trash problem for doing a 'clean-up' (except for the white kind - as in poachers), but it has plenty of parking, nice places for BBQ\lunch, and plenty of bank and boat fishing room.
