SlightlyS,
Let's not get crazy and turn it into something sterile. There aren't septuagenarians waiting in line for roller coasters and acting surprised when they can't get on due to a heart condition. It is the way it is, that simple. Not too many of the bars are ADA compliant either. Should that be forced as well? Besides, There are already busses that cater to that crowd. They have AC, pleanty of seating and stop at Times Sq and Ricks.
Yes, it was sad to see them not get on and it was sad that only a few people gave up a seat.
As far as someone else taking it over? No way.
