Last nite I heard Air One circling above our neighbourhood for a period of time around 11:15pm, since it was not going away I decided to circle the block and ran into two police cars as well as 50 or more people standing on Sask drive with more arriving from down in the pit.
Must have been quite a gathering as the band was quite loud, which generated a noise complaint.
If this type of gathering happens in the future, advise EPS 780-423-4567 early on , and then they can prepare to move people out of the park. Noise Complaints/Disturbances can trigger an earlier response, and if not earlier then they should not be in the park after 11:00.
