On the website it says if you buy a spring pass and get 1/2 off on a summer pass. I think that would be cheaper than just buying the pass alone, it should save you like 300 bucks, assuming that pass is about 900 bucks.
notice how its hard to find the price for the summer pass? and how it was so easy to find the price for the spring pass? they know they are fucking people over, i think they are a bit ashamed of it, as they should be. If you charge somebody 9 bills for a pass you should at least let us in the windells park, or make public better than what it is.
