Why is it CB vs. 2-way radios (CBs are 2-way radios by the way). Just like carrying an air jack and a Hi-Lift, is is a good idea to have more than one type of communication method. While CBs are the most popular, Ham radios has much better range and clarity, and GMRS / FRS radios fall somewhere in the middle. Most government agencies now monitor 2 meter ham frequencies as well as CB channels. And while getting a license doesn't preclude someone from being an idiot, those who have worked for their "ticket" generally have more respect for the amateur radio hobby and those in it, using radio communications in a proper manner.
With the price of amateur radio equipment becoming much more affordable, I think it is a good idea for anyone involved in an outdoor hobby to consider getting their ham radio license, in addition to having a CB and FRS / GMRS on board...
