@Jim Bennett:
Frontier has pretty much everything on the "other side" of Lehigh river, including the Lehigh County itself. Some areas in the Poconos are still Verizon, but going towards Wilkes-Barre and Scranton is Frontier territory once again.
@dexman:
I guess a lot depends on where you are...in NYC, T-1s are still a very popular circuit...and hopefully will stay that way until my retirement...
