The four sisters are actually four smoke stacks for the local coal power generation plant (Lakeview Generating Station in Mississauga, Ontario, Canada) that is being de-commisioned. Ontario Power Generation have scheduled June 12 as the date they will detonate blasts to bring down the "Four Sisters."
Official activites commence at 7am on the R.K. McMillan Headland at Lakefront Promenade Park.
The detonations are scheduled (weather permitting) to occur at 7:30am with the stacks coming down from east to west.
The entrance to Lakefront Promendade Park will be closed from 6:30am until after the demolition.
I'm thinking a 24 exposure roll of HP5+ and the 2 fps winder for my ME Super will do nicely.
