From a posting to the newsgroup rec.guns on March 4, 2000:
===========================================================================
Consequently, earlier this week I sent a letter to the Sheriff's Office in
Greensburg, PA, requesting information on the application process.

In return, I got a single paragraph letter from the Sheriff:

"Dear Applicant:

We are in receipt of your request for a Pennsylvania License to Carry Permit. 
Before considering your request, we require a detailed letter explaining why
you wish to have a permit to carry from our county and state.  Also, we require
a copy of your out-of-state carry permit.  We generally do not make a practice
of issuing permits to residents out of state, but if there is a valid reason
for your request, then we will take it into consideration.

Sincerely, etc."
