The first thought that came to mind when I read the Weekly Prompts: Celebration challenge was fireworks, more specifically Canada Day fireworks.
I suspect they came to mind because this winter I have been digitizing my slide archives and have recently made digital copies of two sets of Canada Day firework photos.
The 1999 Canada Day fireworks on Monument Hill, Punnichy, Saskatchewan.
The 2007 Canada Day fireworks on the Lake Huron shoreline in Southampton, Ontario.
The 2017 Canada Day fireworks at Bluewater Park, Wiarton, Ontario.
