I noticed a decline in the number of people in my area out driving around when gas prices went above $4 but, the stores were still packed as well as anything that had to do with entertainment. I was able to walk down the MUP to the library or to the market and it started to get quiet. I also noticed fewer people on the commute to work. Now that gas here has gone down to sub $2, people are out EVERYWHERE.. Traffic is all backed up, the stores are jammed...everything is back to where it was. I don't see any belt tightening. I haven't observed people pushing empty carts around in the stores....
