Gaining momentum?

With Maine and New Hampshire having both passed Constitutional Carry laws, I thought it was pretty neat that a person could drive from the Bay of Fundy to Burlington, VT strapped and without need of a permit.

Looking at a map posted by NJT the other day, it occurred to me that if either Nebraska or Iowa went to permitless carry, one could drive from Biloxi to Couer d'Alene without requiring a permission slip for your blaster.
