In the distant future, I may be in a situation where my PCs will have a huge bounty (or something similar) on their heads. The idea here being that they are actively being hunted and pursued by a large group of people, to the point that they would be unable to go pretty much anywhere for fear of being captured or killed. To put it in more meta terms, this would essentially be an adventure unto itself rather than just something that occasionally pokes its head up.
Has anyone done anything similar? How did it go? What did the meat of the adventure look like for you? Has anyone used a written adventure (even if you heavily modified it) as a framework?
NB: I'm intentionally keeping the details of my situation vague because I'm not currently looking for solutions to a problem. I'd just like to hear stories of other GM's experiences or ideas that you've had for things you'd like to run.
