Government Waste

So, we were on vacation last week. While driving through New Hampshire we noticed one of the biggest wastes of time, money and resources that we have seen in a while. They have signs posted EVERY 0.2 miles (yes, 0.2 miles) stating that you have gone another 0.2 miles. Example: mile 46 ..... mile 46.2 ..... mile 46.4 ..... mile 46.6 ..... mile 46.8 ..... and so on the ENTIRE WAY through the state. Why do they possibly need this many markers? Not only was it a waste, it made the trip feel longer.
