Here in Pensacola, just barely touched by Katrina*, only about 1 of 3 stations has gas at any given time. I'm just back from a "gas patrol," and managed to fill up the wife's vehicle after waiting in line about ten minutes. I actually passed on one station that had very long lines; many had no gas at all. I paid $2.69/gal for Shell 87.
* we had several hours of 60-70ish winds resulting in a lot of tree limbs down, absolutely nothing like Ivan or Kat in NOLA.
