Excuse me, I took a break and had a couple kids.
So - most interesting places to run out of gas.
One - the Dulles Toll Road.  Before GPS.  Between exits.  With no clue which exits you are between.  I have to say, toll gate operators are very nice to flustered ladies trying to locate confused, stranded husbands.  They call each other to see who can spot the lost car.  Maybe it's the best excitement on a slow day.
Two - right in the gate of a major toll plaza going out of Boston.  If you tell the gate operator you just ran out of gas, he'll think you're joking.  When he realizes you aren't, he will be seriously Not Amused.
I'm shocked I can only think of two, but I guess those were the most traumatic!
