LOL my first thought when I read the title post was that it sounded like an amateur cleaner. No offense to the poster. This is a good place to ask for advice, and the others have done a good job, but i'd suggest a light sleeping bag. Don't rely on forecasts as the weather can change quickly. I live in the southwest. Guns of all types are readily available. If you are not comfortable with them you can always pick up a cheap can of pepper spray and ditch it before you fly out. If I can be of help simply let me know.
