But these strips are inaccessible to most pilots living in the area. They are run by tightly knit groups.
They are indeed, the way to get in with the tight knit groups is to make yourself known and spend time with them. Maybe have something to offer from time to time. You would be amazed the doors that are opened when you are pleasant to people. You know dropping a spark plug off or a tyre to someone in need. Rather than treating everyone who chooses not to do your type of flying like they are muck beneath your feet. (*that was a generic 'your' not a punt at IO before he goes off on one).
There are 20 strips within 10 minutes of me all run by tight knit groups and all open to me. The strip flying side if GA is exciting and vibrant. Having a strip aircraft like the Auster is a benefit of course!!
