There once was an ad for Camel's cigarettes that said "I'd walk a mile for a camel." People found the double meaning (cigarette and 4 legged animal) catchy.

The second point could refer to the woman and her strange actions because she is frightened of the unknown, and often being in the outside exposes you to things you can’t always escape from. King uses this to convey a fearful setting that a reader can relate to.
I hope this helps :)
