Wow, that's a mighty steep toll. Up until I got a job requiring travel 7 years ago, I'd never consciously thought about toll roads, never had been on one. I was amazed with gas taxes and all that people would pay for using a road. Of course, I was also amazed people would pay for bottled water, and that's huge, I even buy them when I am on the road.
People's taxes pay for the roads and they want you to pay to use them. Why not,they do it with parks and other Government (people's) land.
I have never in my life payed for water. They can do it because they know ANYTHING in this country sells and people will buy it.
