...I flew into an airport with a control tower. I learned to fly at a tower field (CPS, back when it was called Bi-State Parks, and it was a "control zone", not "class D"), but after that I rented occasionally at uncontrolled fields, then bought a NORDO T-Craft, then a 10 year hiatus from flying, then paramotors, ultralights, and finally the Fisher I have now, still based at an uncontrolled field. Little grass fields with dilapidated hangars, antiques, and homebuilts are my style, not acres of concrete, security gates, and "follow me" trucks. But yesterday I needed an excuse to go somewhere different, to test my new GPS setup in preparation for flying my new Starduster 1000 miles home next week (hopefully!), so I decided to go to HFD for lunch at the new restaurant there. No problem, tower didn't seem to have any trouble understanding me (open cockpit) even though I had trouble understanding myself afterward on liveatc. I had trouble understanding the tower only once when they said something unexpected (asking if I'd been there before; people have mistakenly landed at the closed airport just across the river and they wanted to make sure I knew HFD is on the west side, which I did). Only place I messed up was not reading back my taxi clearance when contacting ground for departure (never had to do that back then). And they kept asking me where I was while airborne (small wooden aircraft, no transponder, 55mph cruise speed). All in all a good experience and stretching of my comfort zone.
