My vote is for Lancaster County. Now here's the plan. Tell your wife you are taking her to the Lancaster outlets shopping. Drive directly to Duke St. in Lancaster. Go to the Court House. Empty your pockets into the little basket going through security. Make a right and go down the hall and turn left into the Sheriffs Office. Tell one of the smiling friendly ladies You would like to apply for a Pa Non- Resident CC permit. Tell them you are from Delaware and watch the smile on their face. (One suggestion: I filled out the application on-line and waited to sign it in their presence) That made them really happy because they didn't have to explain it again.
Show them your De. Drivers permit, and your DECCW, along with $20.00. She will take all and go make a phone call after asking you to be seated. Next she will call you back to the desk and tell you to go see the lady taking pictures. She will ask you to read and verify the info on the permit , take your picture and seal it in a laminated cover, hand it to you and thank you . 20 minutes, your out of there Happy, Happy, Happy.
Now if you have time, take your wife to the outlets, after all, that is why you went to Lancaster isn't it?
