I can tell you that the HAM is very useful when you get out and about and away from the rest of the world and need some help.
Expense is no longer an excuse. $14 license, $120 Yaesu 2M, $35 mag mount antenna, and you have a basic set up. That is less than the cost of 3 tanks of gas.
No more crackling garbage messages, no more half of the radios not working, no more having to worry about the local trucks interrupting your transmissions.
And best of all, unlike most of the CBs out there, you can buy radios that are not made in China
