I'm a city boy these days, but in the last few years I've found a great deal of pleasure in clearing brush on my Aunt's property. You start with a tangled, imposing, wicked mess, and when you're done you have a nice clean open area. It's a tremendous surrogate for the problems that don't have such... not easy, but satisfying conclusions.
Plus you get to play with chain saws and other fun implements, git re-al dirty, and get a lot of exercise.
Kerry said he clears brush too, he just doesn't have pictures of it. Ha ha ha.
