Well, not exactly wilderness. Lake Odell Resort in Oregon is one of my very favorite places. We rented a nice cabin and hung out for 3 days in the snowy forest land near Crater Lake National Park. The kids (and parents a few times) could sled right out the door of our cabin down a small hill, down the path between the cabins, past the lodge, and down to the lake's edge. The dog had a ball except for his plunge into the icy lake, which freaked me out as much as Chico.
No internet, phone, or TV for 72 hours. I guess I could live without them for longer, but glad to be back in the zone.
