Vincent,

Please explain why it's irresponsible. I understand that very few
domestic airliners and commuters have GPS. Does every mililtary
aircraft have GPS? Is it irressponsible to fly a J-3 NORDO, even into
OSH?

Well, I think I gave the reason. Remember the two bozos flying over Washington, DC and how much they hurt all
of us?
Airliners have other RNAV equipment. The military too. Do I think a NORDO J-3 should have a handheld GPS?
Yes, I'd strongly recommend it.

The poster said he NEEDED a GPS. That suggests dependency.

Not to me.

It's common knowledge that many recently trained pilots have not
learned to navigate well. It's often been discussed here.

I don't know. Sounds a lot like the "When I was young, x was better" fallacy.
