A chief complaint of mine is that the "ranger" drives slowly through the campground loop in his vehicle with the window rolled up (and probably the air conditioner on) at the state park. The campground isn't that large...just three loops and probably a total of 40 or less camping sites.
I believe he should park his vehicle and walk each of the loops to see what is going on, be available to answer questions, and have some interaction with campers. There is already someone staffing the entry gate, so he doesn't have to be there all the time, and I know this is the only park he has duties in.
