This recent string of locations was all chance, I was riding around on my lunch break and took a wrong turn, stumbled upon an entire city block that has been bought up and rezoned. They were only abandoned within the last year and should all be gone by the end of summer at the rate the demolition crew is currently working. Because of that they cannot easily be found with the usual method of spotting clues from satellite view, these last few places all look occupied from space.
That being said, finding this block taught me a pretty simple lesson, follow the development. The Lower Mainland and greater Vancouver are growing at an insanely rapid pace, every residential neighborhood west of Hope is growing outward in all possible directions like an organism, eating up every old BC box in its path. You'll find more derelicts on the edges of neighborhoods than in the middle, and they don't last very long. It's the properties with the big backyards that are being bought up and turned into condos or suburban clusters, and fortunately they're also the properties with the longest and most overgrown driveways, providing plenty of cover from pedestrians and neighbors.
An easy way to spot rezoned properties is to just keep an eye out for these signs, they usually mean that the property behind them is no longer occupied.
It also helps that I commute 140 km or more every day. I absolutely love riding so I only take the back roads to/from work and I try to change it daily, exploring new side streets each time.
Maybe one of these days we ought to go for a ride around Langley or something. Or better yet if you'd like to make a bit of a trip out of it I could show you a pretty cool spot out in Chilliwack River Valley and a great dual sport/ADV riding loop through the mountains.
