Oh wait...air travel isn't a right and you know you may be searched by agreeing to fly on airlines, so I'll have to re-think my position here....Hmmmm.
Yep, I'll drive if at all possible.
Exactly. Signs near all the checkpoints have wording to that effect, something like "you're free not to be searched if you choose not to board an aircraft".
It's been a while, but back when I was renting planes and flying myself around, I didn't go through any screening and could carry whatever the heck I wanted aboard my own plane. I imagine there's more security between the general aviation and commercial airline sections of airports these days.
