Ok since I work in a prison, I'll ask the experts lol
Most said what's ham, and gmrs how would I get there address from letters and numbers. One said if there over two hours away it's not worth the time to try it because what if someone is home or what if there poorer than me it would be a waste of time. No, I didn't ask them but after 18 years I've talked to a few about crime shows so serval ideas have come up.
