Whats the MOSt $$$ you paid for gas in the USA?

The media always says that gas prices rise in the summer because of the "Summer driving season". I think that it is a scam devised to allow the oil companies an excuse to gouge us even more.
Anyway......
What is the most that you have ever paid for gasoline in the United States? I'm talking about regular, pump gas...NOT race fuel. Think of that trip you took where you found yourself waaaaay off the beaten path and the only gas available was at some grungy independant station...something like that.
For me, the highest I ever paid for daily driver, 87 octane gas was in late Summer 2008 when oil prices hit nearly $140 per barrel. I remember paying almost $4.50. My Charger needs 91 or better. In 2011 I paid $5.08 for 91 in Van Nuys.
