It is out of the way and people tend to stay in specific areas. My thought on the antique car return would be the cost of gas (they could probably figure out how to do electric) and the pollution it caused. Never could stand the exhaust smell and it traveled around. Usually once something is gone and people are used to the absence, it is difficult to bring back interest. I don't think it would thrive anywhere actually, not anymore. People tend to move on to other things. And they don't need to bring new rides every year. They could improve general things and get pretty much the same effect from my point of view. Would hate to see the tower garden area disappear as well.
Barbecue place sounds like a plan; no way could I ever eat burritos at an amusement park. But no matter what they do, or don't do, you are right, Mr. Roberts. People will still complain.
