Those are good points, Marc. Common sense isn’t so common, it would seem. Would most of us go to a new site and just launch without at least looking for a bit of information about the place first? Probably not (at least, I hope not).
Keep in mind that there is no “day use sign up sheet,” since day use is no more.
We do have the approach patterns on big posters in the LZ, but as you said, not sure how many read those. I’m not sure a sign on the stairs would help, but we could certainly try that out. In talking to pilots on launch, a scenario I’ve run into more than once is visiting pilots driving directly up to launch, so any signage in the LZ would be moot.
What seems to help (I try to do this as much as I can, but I’m only there usually once a week on the weekends) is saying hello to pilots that you don’t recognize and get them engaged in a little conversation. That makes it really easy to point them in the right direction for information, getting their membership squared away, and giving them a site intro if they haven’t had one already. We’ll need EVERYONE to participate in that to make that effective, but I think it could do the most good.
