Some in the last couple of weeks...
1. I fly in to Flabob for lunch at the Silver Wings Cafe. First table just inside the door, a quite elderly woman starting in on her blueberry waffles says: "Was that you in that little blue and white airplane? What a pretty airplane!" A good way to start a conversation! She flew out of Flabob for years with her husband before he died... She knows a pretty plane when she sees one.
2. I'm getting flight following from LA Center. The controller says to me "RV 6 Delta Papa, I'm going to hand you off to approach in a minute, but first I have a few questions." I say, "Go ahead." There follows: "Did you build it?" "Carbureted or injected?" "Constant speed or fixed pitch?" "And finally, before I let you go: Tip-up or slider?" I could hardly believe it, the sector is busy, he's handling a fair bit of traffic, but he took the time to ask about my RV. Then he really did have to hand me off, before I could ask him about what he's building

.
3. I've been parked at the Nanaimo BC airport (CYCD) for 5 days, time to depart. I go into the terminal, and ask the first official-looking person I see, "I need to get to my private plane for departure this morning, how can I do that?" She very nicely says, "I can escort you to your aircraft." Then she kind of does a double take and says, "Are you the one with that little blue and white plane with the top that kind of flips up? I noticed that one when it came in." That was 5 days before, mind you.
Etc., etc. It is one of the things that definitely adds to the fun of flying an RV.
