Yea, the 2011-2012 season was the first year I was a passholder and then they were only doing the weekends/holidays thing with Slide Brook. The 2012-2013 season was when they switched to running it whenever conditions permit. Maybe it isn't entirely needed, but I personally like that they run it all the time now.
I agree with you. I think it made things better. In addition, I bought a pass to ride the lifts and not a bus.
