Yeah I'm in Terrebonne.
All my backpacking stuff is currently floorless. I dont usually find the bugs to big a deal in a bag, in the quilt tho is sucks so I run the Jimmy tarps bivy.
I have a 6x9 Jimmy tarps, a Mt Shelter Lt, and a new seek outside Eolus on the way it you ever want to check some stuff out.
I lived in Central Oregon for many years. I gave up on a tarp. It was either bugs in the Ochocos or blowing dirt around Sisters. During the winter months I would take a tarp into the Mill Creek Wilderness area without any issues. But, in general I just prefer the full coverage of a tent.
