Yep, I saw it - at 3 stations yesterday down in the Texas Valley. Sorry, didn't take a picture.
I saw one station on the way down into MX. When we were on the way back, my friends stopped for gas at a station with 2.06 as the price and I asked why they didn't go down the road just a piece, cuz it was $1.98, but he said he thought it was a fluke. Good thing 2.06 wasn't bad, cuz 5 minutes later we were passing the intersection off the highway where they were $1.98.
I really didn't believe I'd see gas under $2 again - so while the economy and my retirement bucks are devastated, I can better afford the gas at least.
