It would be much better with trees and might get used more. The problem as it stands now, is it's a huge bare section of grass, and not even good quality grass. There's almost nothing useful about it.
What I'd like to see is a few small buildings along the path between Fort Calgary and the pathway, sort of small village of building 1-4 storeys. It could be built and would still leave lots of room for festivals, etc..
The blue areas could be patio space. It would have the potential to be an awesome hangout spot. The pathway from Louise Bridge to Inglewood could become Calgary's version of the San Antonio river path.
