It is almost 4 miles if you go by the google directions, which takes the road, and that is a long ways around. If you look at the map it would be much, much closer and a straight line to cut through. ETA, it would be less than 1.5 miles going this way. Also, DS was able to go to Haleighbug w/o any repercussions so I guess he has a pretty wide range that he can travel. And 1 more thought, as the article by Martha Stewart stated, the ankle monitors can be removed.
Here are the Google directions
