Yes, its finally happened. I saw people swimming in Greenaway Pool. I drove by Greenaway Park twice this afternoon at 3:30 and 5:10 and people in the pool.
I checked the City of Surrey's web page for outdoor pool times and I have found a link http://www.surrey.ca/Living+in+Surrey/Parks+and+Recreation/Recreation+Services+and+Places/Pools/Outdoor/default.htm
The only thing that is odd is that Monday to Friday Greenaway Pool's hours are 3 to 4pm and 6 to 7:30pm so that doesn't really explain why I saw several people in the pool after 5pm today. But that's the link that shows the hours for all outdoor pools in Surrey. How accurate it is, who knows.
