Thanks for sharing. In my past road trips, gas cost
has always been a consideration. I wanted to save as much money as I can on road trips so I usually ask a friend to go with me. What I do is I split all the expenses -- gas, tolls, parking, etc -- evenly at the end of the trip. I think if you can't afford the cash outlay for everything along the way, then let different people pay for different things, and keep track of all the expenses and who paid for them, and just even things up at the end.
