Much like my hubby up there ^ I'm not scared of too much. I do have a thing about escalators, so small-town-girl I understand what you mean. Its not the escalator its the rubber hand rail thing that creeps me out. I can't touch it. Its just germy greasy gross.
I also have a thing about being stuck someplace I can't get out of. I can't sit on the inside in a booth at a restaurant. Large crowds, that sort of thing.
I guess just your basic claustrophobia.
