Gee OB- after we gave you all the math....
I would likely agree with your hubby- there are places here that always have cheap gas, and I wouldn't use it.
I still remember once my car had run out of gas at 4:00am, and we pushed the car past a Domo to hit a Texaco station. Domo attendant even asked us what was wrong, and was surprised that we wanted to push the car a few more blocks.
