Upon considering my escape plan more carefully, I realized there is a problem. The main street runs parallel to the railroad, perhaps less than 20' away. The two of them intersect the nearest interstate highway. The exist/on ramp are very close to the intersection.

(1) If a spill happens, the main street will probably get shut down.

(2) I may not be able to get on the highway and high tail it out of there.

(3) My roughly triangular town is bounded by the interstate on one side, and the railroad on the other. I feel kind of screwed. I may need to get near the source of the spill in order to get away.

So the big question is, if a spill happens, how close can I get and how far away should I get?
