Some great points Shawn, but I wonder if it's that clear cut. I now
live in Oregon where most people learn basically how you described.
Something that's becoming increasingly clear is that the pilots around
here really don't like using the radio. They get uncomfortable talking
to controllers, and talk about how they never file VFR flight plans,
use Flight Following, or any of that.

The other day, I flew to Portland. When I mentioned where I was going,
all the guys in the lounge looked both interested and nervous, and a
couple of them made comments to the effect of how they don't feel
comfortable in controlled space (presumably class D-). I've heard
another pilot refer to class C as his personal class B.

Where I learned, I didn't have a choice but to pick up the radio stuff,
and it took hardly any time. I don't think I missed out on learning
any flying basics, and the added load during training with the
instructor onboard helped me learn important cockpit resource
management. I have a feeling that people who learn in the boonies
might be at disadvantage when entering stricter airspace. Not because
they are worse pilots, but because they're having to spend brainpower
figuring out/using unfamiliar radio procedures while navigating in a
high traffic, unfamiliar environment. I had that, but I learned with
an instructor in the right seat to be my net until I had it down pat.

I mentioned that I had transitioned class bravo down in SoCal, and only
one other guy at the lounge had done that, and it was this alien,
exciting thing for them to hear about. These guys are way better
pilots then I am, but high traffic/class bcd airspace intimidates them,
and that's just not right.
