O/T Firearms 101: Have some questions on laws-

:read2:

First off, I am only interested in owning a fire arm for personal and home defense. Not interested in collecting, competition, etc. I am currently 20 years old, 21 in September. Few good friends of mine carry with their concealed weapons permit out in Nevada, I feel it's a good idea to do so.

Which it is my understanding, once I hit 21 I can apply for a concealed weapons permit. Yes? If so, can anyone share what is necessary to go through the application process?

Up and coming here at the end of the year I will have a cross-country journey. Headed from Florida all the way over to Nevada. I'll have a fair amount of brand new snap-on tools, u-haul with my stuff, staying at various holiday-inns and such. I would like to be able to carry something in my vehicle, lawful. Now since I will be about in a different state every day during that trip, can anyone say what is allowed? Does it need to be so many 'steps' away from use? Loaded, unloaded?

Thanks! :read2:
