I've been trying to remember all of the great wilderness areas around Portland that I can take Grover to and let him run around. We tried these lakes last weekend with Timmy, but they don't allow dogs, so Grover and I returned today sans pooch (sadly) to check it out. G liked the observation deck best - not for its view, but because the steel grate floor allows you to see the water below and makes a great noise when you run across it.
