Just got back from killington and I wasn't in rails to riches but I checked it out for a bit. Since the pictures aren't really that clear, the setup was a 20' urban down bar, the dfd you can see pretty clearly, and a gap on to a 20' down box with a flavor kink at the end.
A few kids were SLAYING the down box. Actually my favorite tricks I saw were on the box as opposed to either of the rails: 2 on, front 3 up, pretzel 2 out of the box and someone else threw a (granted, pretty sketchy) misty 4 out of the flavor kink which was dooope.
It looked like a really fun setup despite the pictures looking questionable. Definitely a good job by killington
