Ended up staying in a park in Mountain Home ID. A bit of a drive to Birds of Prey......
We did go in the Jeep, there is some BLM land between Boise and the site, but didn't look friendly for our size coach. Also seemed like a lot of people doing target shooting in the area which terrifies our Border Collie so we're glad we didn't.
One thing to mention is some boondocking on the Snake River just downstream of Swan Falls dam. There is a gravel road along the river off a paved road to the dam. Bad thing is about a mile of 7% grade getting into the canyon.
