As I way often say, you are on your own, do your own thinking and plaining, do not expect uncle Sam to save you. Right now there are hundreds of thousands of people stuck on highways leading out of Houstan, out of gas, out of fuel, in strange surroundings. No ones fault, I am happy I bailed out of the great traffic ram while the bailing out was good. Much better to deal with Rita at home then on the sidw of the road.
Sounds like you made a good judgment call. The roads seem to be clearing and you might be able to leave in the morning. Signing off from Jersey. Godspeed to all of you Texans in the path of storm.
