Or contact the local high school to set up an introduction for them, visit the airport, flights, etc.
I don’t know about your airport, but when I first arranged to meet for a discovery flight, as I drove into the airport at the gate was a sign “military personnel only” etc. among a bunch of signs. I’m on Norway, but I’ve seen similar in the US at small airports. Anyway, the airport IS military primarily but they also open it up for GA. the sign wasn’t clear, at all, but just inside the gate the road forks and the right road goes to the restricted military area, the left to GA parking.
In any case, to a first time visitor it tends to make them uneasy and unsure if they are allowed to drive in there. This seems really counter productive to me. We do have folks, non pilots too, that are locals and know they are allowed, that go to a bunch of benches where they can watch takeoffs, landings.
But I mean, it seems like one would want advertising and a “welcome” sign at the gate. Maybe “come on in and watch or talk to someone about flying lessons”.
The small local newspapers too, no ads. They wouldn’t cost much.
I think nowadays most people do not think they can just drive into a small local airport.
I think too, just planting the idea in younger folks that they could learn to be a pilot could really help.
