<<<<---- Then........
In its death throes........
The sacred and coveted-by-underclassmen Senior Lawn is no longer fiercely protected by the senior class.  The freshmen don't take long detours around it for fear that they will be canned.  In fact, they seem to have no qualms about parking themselves on it during lunch or brunch! 
There is no right-of-passage, no paying one's dues; no initiation, nor even any age minimum to be on the lawn now.  Seniors allow anyone on it these days.  In fact, the seniors DON'T EVEN HANG OUT THERE!

It's a travesty, but it's no wonder - the Senior Lawn is looking pretty shabby these days.  I am not sure I would want to hang out there any more, either, with the relics of days so long gone by that they are being eroded by time, the elements, and the click clack of little wheels (skateboard wheels, that is) all over them.  There is a general lack of tender loving care and attention being given these gifts from classes of days of yore.   
Harold Brooks stuffs an underclassman in a garbage can for trespassing on the senior lawn, a mistake he will never make again.

2007 Update:  The Senior Lawn is no more.  The quad area has beautiful new landscaping and seating areas as well as a stage.
