It's just one of those odd things you notice (Statue of Liberty Isle), when visiting NYC.
This was a customized ATV. I stood and admired it. The total cost? I would take a guess that the National Park Service spent at least $100,000 to buy this and outfit all the stuff on it. This is to serve an island area of roughly forty acres. If you can the walking areas, there's maybe three miles of sidewalk.
The thing is.....if you look at much weight it's carrying....I doubt if it gets more than fifteen miles per gallon at best.
