Day 1-2: GORGEOUS!!! Perfect sunny & breezy weather, insane views from the campsite. Very quiet and only a handful of first come first serve sites. Simple toilet facilities. Fire rings. All the makings of perfect car camping. 

Day 3: The wind dies down and OUT COME THE MOSQUITOS. I camp a lot, I have done backpacking/car camping/overlanding in all seasons and encountered bugs-a-plenty. The mosquito swarms in mid-June are ABSOLUTELY unbearable. No amount of bug spray seemed to matter, they were flying into ears/eyes/mouths and into the flame from the cookstove by the hundreds. Not that many bites for the number of them, but I you will be COVERED in them. We ended up bailing and getting a hotel in Leavenworth for our last night because they were so bad.
