On rides on I-78 west to Harrisburg, I've only noticed 2 Shells. One of them always seems to have "No gas." signs on their pumps.
One Texaco became a Valero, and two stations recently became Citgos.
Now if you want BP, it seems Philly is swimming in them.
BTW, Steve, my valves called me the other day to thank me for the Shell..... Collect...... nervy cheapskates
(I'll show them. Feed them no name brand gas.)
