I don't know the folks who did this little video. Evan Oxland found it and sent it to me yesterday.
He wondered if it was one of my arches. I wrote back and said yes it was. It was one we built out west in Burnaby BC for N W Landscaping and Stone Supply. It was a beginners workshop.
It's three years old and I was happy to see it is still looking well and that someone liked it enough to do a video.
