I have to say when I first saw the initial designs for the park I was disappointed, but it has grown on me. It's not necessarily going to be a marquee attraction but will be a nice space, replacing a swath of surface parking with something far better. I still wish there was more when it comes to recreational space (maybe basketball courts, tennis courts or a skating rink in the winter). I also agree with the sentiment that it should be bigger, it's more of a neighborhood park, I was hoping for a destination Central Park that would attract visitors from across the city, but I don't think that's going to happen, at least not to any large degree. This would be the perfect place to build an "Edmonton Sign" like the Toronto and Ottawa signs in front of Toronto City hall and in Byward Market as a photo spot.
edit: Speaking on skating rinks, is there any way that "The Clearing" in the design could be converted to one in the Winter time? I think this would be super important to keep the park active as the months get colder, so that it doesn't become a semi-abandoned, sketchy place between November and March.
