I don't know where Gary was camping around Bend ... but I do know there's that great Tumalo State Park located on the Deschutes River 4 miles north of Bend.
I doubt that there's many rigs in there this time of year.
We stayed there years ago and it was real nice then. There's fine trout fishings up in the mountains around Bend, too, especially if you hike up to them with an inflatable boat.
One of the best things in Bend way back when was Dairy Queen with it's fantastic Blizzards!
