If there are any horse farms around I am sure they could put him to work. My girlfriend has friends that operate a smaller horse farm and the times we have gone down there for her to ride horses I somehow got put on maintenance duty. The amount of manual labor involved with horses is way more than I ever expected. Some of their neighboring farms always have some high school kids working on them. If there is one of those around that could be a good back up option if he can’t find any ag farms to get on with. Long days of manual labor will definitely be a good character development exercise for him. Good luck to him.
