WE took up a collection of $250/person to ride the bus and that was to cover gas for there and back and any small mishaps along the way. Ended up it cost about $50- $70 to fill it up and we had to fill up on average about every 400 miles. It got anywhere from 9 to 12 miles to the gallon. It was a really really good time and we hope to make it an annual one.
