Re: [PSUBS-MAILIST] fascinating stories

Oh, there's a bunch of us on here old enough to remember curb feelers.  If
fact, according to my wife, our car has them now only they take the form of
alloy wheels!

Seriously though, I have thought about some things like that on my sub.
Every time I see one of those pendent type flags waving above a kids bike I
think what a good idea to surface a flag before the conning tower breaches.
The one draw back is it's another thing to get tangled in something.  I'm
considered a thin short wooden flag pole now.  Something that will break off
easy if it needs to.

Curb feelers.......  I-don-no.......
