What if the interstate or other major routes are bogged down with the other people wise enough to evac during this serious calamity? I would definitely say the maps are worth it, but hopefully if you were taking a car trip to LV you would already have the nessecary maps and not need to spend your emergency cash on them. I can get you anywhere if my map is good enough. I always have maps of my local area, city maps, state maps, a state atlas (60 pages of topos), and regional maps of the entire east coast. And though I like those cool new vehicle GPS, nothing beats paper maps.

For those of you that are members, AAA is awesome about giving you maps of whatever state/region/city you need, at no extra cost other than membership.
