They dont seem to have the shape of a wasp, I don't think they are yellow jackets but I could be wrong. They seem to spend a lot of time at ground level, and really seem to like the sugar water I put out for them There are a lot of racoons here who are hip to coolers and trash, I keep a very clean campsite. All edibles stay in my car as the park staff recommends and I just make certain my car is in the shade.

After a 4 mile mtb trail hike today, I took a chance and tried a small ride on the easiest trail. When my muscles are warm there is little pain and this time I was able to mtb almost 2 miles before my bent boob started complaining, yesterday I couldn't even ride on the campground road! Progress
