Just 6 miles north of Bishop is one of our favorite campgrounds just off the highway about a half mile.
It's Brown's Millpond Campground!

The operator in there lives full time, and if you go ask even if she is closed and all you need is electricity, she will often let you stay. If you tell her Mike and Carole send you there from their truck and camper she might remember us.
