>wherein Schuylkill is pronounced skookle.

Hooray! Someone who knows the correct pronunciation of Schuylkill... :-)
One way we Berks Countians immediately identify out-of-towners is their mispronunciation of Reading (which is supposed to be "Redding") or the name of our neighboring county of Lancaster. Non-Pennsylvania Dutchies tend to say "Lan-caster" instead of the proper "Lenkister."
