I'm driving home to Arlington this weekend, and I'd like to split the cost of gas/carbon footprint with someone. I'll be leaving from Duke around 1 pm on Friday, and leaving from Arlington at the same time on Sunday. I'll drop any passengers off at Ballston metro. I can fit up to three people in my car comfortably.
Suggested gas contribution: $15 (less if more than one person splits the ride with me).
