G-Emma,
Just my personal opinion, but FWIW I disagree with F3G's disagreement, precisely
because he considers A/G fields to be the most challenging ...
I learned at a busy, regional airport, with full ATC and huge hard runways.
If I had to do it all over again, I would without a second's hesitation learn from the shortest grass field legally available, with an A/G.
You're learning to fly : you've already had a considerable amount of experience in talking ...
I know there are those who have learned to fly at small fields who are terrified of having to enter ATC domains, and I've never understood why. Your training will provide enough of the basic "patter" to allow you to enter and transit ATC zones, and in my experience, most ATC is extremely helpful to those who sound a little "new" to the game (OK, there are exceptions, but not that many).
You, on the other hand, will never have to worry about joining a busy circuit at an uncontrolled field, which scared me positively witless (that's a spelling mistake
) the first time I had to do it.
I reckon you've got it the right way around - good luck with your PPL !
