We learned quickly that the sites we thought we liked were wrong for us.
We used to look for: quiet, secluded, lots of trees (including pine trees), near a stream.
Last year, was our first summer of RV'in and found out our mistake on the very first trip. It was a cool, damp weekend. The black flies were out and had breakfast, lunch and dinner on us and the dogs. Of course, they are worst near water!
The trees were a real obstacle to park in between, nothing like trees to learn baking in nice and straight in a hurry. Also learned to keep enough room for the slide.
We now look for these sites that I used to think were ugly.
Drivethrough and paved or level away from pine trees and their needles.
We do like the shade in the summer, but sun spring and fall.
We have no kids so try to stay away from play areas and pedestrian paths, the dogs like to bark
