Re Coastie09's comments:

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.

Definitely agree with you on AAA membership for driving maps. I get my money's worth on that feature alone. I also agree that one would need them to find the alternate routes. I remember when Houston was was being evacuated just before Hurricane Rita struck. I live in Dallas and couldn't believe the traffic problems here and we are 3-4 hours away. Also, the gas stations in Dallas began running out of gas because the evacuees had empty gas tanks when they arrived and needed to fill up before they leave (not that I'm angry about this, I'm just stating a realistic event).

I think that were not evaluating the LV situation properly. For example, what is the time of the year. In January, I doubt that I will be heading northeast towards Chicago.
