Usery Park is near impossible to get into during the winter. Its a nice park, with lovely views, but every snowbird in the area knows it's cheap, close to everything and has hook ups. I spent my first nite there in the overflow area.. a big parking lot, where they line you up in arrival order. Fortunately, my friends and I were #s 1&2 in line and were able to get spots the next day. Not together, but at least we got in.
