Interesting thread. Mostly, but some junk that I just passed over. Last time I was at the SEC gate it was clear that I was not wanted, and it was locked and had high walls either side. But that was years ago. The thread is so long that things like access issues and film crew usage and ownership have changed many times over the years.
Good map at city of coquitlam site. Start at
and read about what's on the Qthemap at http://gis.coquitlam.ca/apps/qthemap/
and Choose Basemap = Coquitlam Imagery 2012
and explore to check out what's along Quarry Road.
You can zoom in to 1:564
, which should let you see the dogs, if any.
Where is the SEC gate, if any now? If the gate location was just past Munro Cr. as I think someone said, then there does not seem to be any gate there. But there's a black truck parked the far side of the bridge over the creek. And the gate could be a bit further up the road in the areas where trees cover the road and you can't see it.
You can toggle Map Contents to get land use, property ownership, at some levels the trail from the road up to Munro Lake. For ex., the property just past Munro Cr bridge is 4972 Quarry Rd.
You can also go back and select an earlier Coquitlam Imagery year: 2003, 2006, 2009.
I checked the 2003 and could not see a gate on the road near Munro Cr.
