Today the price of gas is $3.859 at costco. According to my GPS, it cost me $1.50 to get home and another $1.50 to drive to westwood. Interestingly, i was stopped for 1/4 of the time it took me to drive from costco to home. The drive to westwood slowed me down so much that i averaged being stopped for one-third of the time. Looks like it would be better to drive to costco every day than to westwood even though the trip is 1.2 miles longer.
