The laws are different not only state to state, but city to city also. There was a site called packing.org, but seems like that site is no longer around. Another good site to check on the laws across the states is
http://www.handgunlaw.us/ , just check the states you will be going thru. Once you get back to Nevada you can carry a loaded gun with you in the car (in your lap if you want), except in the city of North Las Vegas and Henderson. To get your CCW in Nevada you have to take a class and qualify with the guns you want to carry. I currently have a Springfield .45, Ruger sp101 .357, and for ***** and grins a TEC-22 listed on my permit.
