You can come to beautiful and rugged central Montana and build fence with my father. He is 75 years old and is building 1 mile of fence over steep terrain, through brush in hot dry dusty weather. There is no fancy equipment to run, just 100% manpower, a handy-dandy t-post pounder, a pair of gloves and fencing pliers. Constantly on the look out for rattle snakes since the closest medical center with anti-venin is over 2 hours away. He checks himself over daily for ticks, hopefully finding them before they imbed into his skin. But he says all this keeps him young and being clean is overrated! Between his sense of humor and yours, the verbal jousting would be most fun. I can personally guarentee that you will not only get very dirty, but hot and sweaty as well!
Oooops! I realized there is a minor correction; he is building 10 miles of fence, not 1 mile. Not all of it is over rugged terrain, but that he is working on this year is very rugged. My mom laughed when she thought of your cameras catching my dad scaling a tree if a rattlesnake encounter is too close. It's funny enough for just us to see it, but to catch it on film would be too much!
