I'm not thinking of the surface roads as a place for vehicles to be checked, but on the interstate. Besides, I can't understand not having plans which involve a coworker or neighbor or relative- I think it was Ayers who said it was a team sport. And IF I'm bugging, it is to a shelter, I'd just as soon have someone with me who I can trust at my back.

As for you points about having materials "drafted", I agree, but I also know that if you really try to stand your ground, you (a) arrested, or (b) shot. Neither one of them is a very good option in an emergency. Asking for a receipt gives you a paper trail for later. Besides, be discrete- part of that is having a lot of flashy junk out front sometimes, with the good stuff better hidden.
