In my area seeking out AVgas is more expensive and troublesome than it is worth. Even if you go to the small airports, they are pretty secure with coded gates. My uncle is a small plane flight instructor, so I could probably get there, but still way more hassle than installing and using an in-line fuel shut off with regular E10 fuel. I've been doing it for years and never an issue. Unless you own a boat or a small aircraft already, seeking out those fuels seems like a huge waste of time.If there's a lobby it's still too big of an airport You should be able to find an unsecured small strip somewhere with self serve 100LL I would guess, although not sure how far you would have to travel to find one.l where you live.
