As we cover two states, it's not really feasible to go myself or send a direct employee. The best way we have found is to have contractors go after each other. We try to keep at least two contractors in every area, and we will alternate sending them to a property if possible. in this way, we can tell when one is slacking off. This last grasscut season we caught a few people only cutting enough to get their pictures taken, and leaving the corners full of grass. Crews are always looking to find something wrong with the 'other guy,' so you'll use them more.
