Many of us have run into this when volunteering

I agree with donoln about the need for rangers to have some stability, and have that "known quality" in the parks. But, I agree that some of these hosts have taken it upon themselves to be the "man in charge" far too often. Instead of griping, tell the ranger how you feel about the host. For good or bad. Let the good ones keep doing a good job, and help get the nazi's out. Cell phone videos make GREAT attachments when dealing with a crappy host.
