I have several CBs. None of them are hooked up at the present time.
I have a General Class amateur Radio License, so my short distance communications is either 2 meter simplex or through a 2 meter repeater.
I had FRS/GMRS radios years ago. They were, IMO, no better than a CB. I sold them.
Cell coverage here in the West is getting better, but there are still vast areas with poor or no signals. Cell phones can not be relied on around here.
Ham radio is the best bet. If nothing else works, I can set up an HF antenna and make a contact in California or Florida to get help.
