I fly at 3 different club fields in the area and a number of GA pilots do too. I know most of them, and awhile back thought I'd ask them what their minimums were. Only one (1) of them knew about the "open air assembly", and a couple of them make it a habit of "saying hello" at the club field that's out from town. And that field happens to have a 250' ridge immediately behind it. (absolutely within 2,000k of our runway)
