Since the cost of training is hopelessly beyond my budget, anyway, I
may as well dream of multiengine training.

As a non-aviator in much the same boat, you may want to consider hang
gliding. It's not the "daredevil sport" it may once have been, and is
not a terribly expensive undertaking. I'll probably take my first
lesson in a week or so, at which point I'll decide whether that will be
my primary life focus next spring. Just a thought.
