What's not to like!?
Plenty of open space to throw a frisbee around or just run around playing tag with friends. (yes, we still do that) Night time movies in the summer which is perfect for friends or a date. There's a nice picnic area at the top of the hill and the view up there overlooks some of the most beautiful parts of the city.
Seriously, such a relaxing spot in the middle of two hectic universities. Love it.
