Relocating the water tank

 We moved the water tank from the wood shop to the classroom.  Not an easy task.  21 foot objects do not bend around doors.  We took it out the back door into the parking lot then in the back of the classroom

 Installing the pond liner.

 then slide it under the wall

 My trip to Nedlaw was great I got a chance to see this 4 year old wall with a flat screen TV in it.  They are growing herbs in this wall as well as tropical plants.
