Here's the link to a 19 minute video showing how some spectacular fountains, a formal zig-zag koi pond and a natural koi pond were all installed on a concrete floor to display for 10 days before.....it was all torn down! https://www.youtube.com/watch?v=0S7400hdDYE
WOW how I'd love for those guys to come and make a water feature for me!! I also enjoyed watching the video and wish I could have been there to see all the displays for myself.
Oh, how I miss seeing Home and Garden shows! There just aren't any near us, so seeing posts about shows are especially nice to see.
