I will be hosting a Build-A-Pond seminar on Wednesday, December 16th at my location. We will be constructing a water feature consisting of two falls and a 15'x20' pond. Constructed with boulders and other stones with a rubber liner, not home owner grade stuff. If you're interested in building ponds, this is a great opportunity for hands one experience. The event is being put on by Aquascapes and they charge $35, which includes lunch. Anyone interested please PM me with any questions. I'm located near Leesburg, VA. Thanks.
