A ham radio is an absolute must-have if you’re a prepper. Get one. Get your license. Do it now. I have this exact radio on my Harley. It transmits on the same frequencies as your little family radios too. This has been a best-seller since it came out. The Search and Rescue guys I work with in the local Sheriff’s Office (Sheriff Joe, btw) carry this.
It’s impossible to carry all the food you will need for a week unless you’re eating very high density proteins like nuts. Nuts and dried meat are two of the easiest off-the-cuff meals. Canned food has a lot of water that is wasted during the cooking process. Stay away from heavily flavored or salted nuts. The amount of salt present in the unsalted nut mixes is still sufficient enough to replace electrolytes.
