Arlington Court (North Devon)
BUT .... when I was a lad, I used to sail my clockwork Triang lifeboat, ( think it was 14/6d )on the smaller kidney shaped pond, between the lakes, and the car park.
Went there on hols in late 80s and the council had just filled it in. The outer borders were still there, but brand new tarmac rather than water. Grrrrr.
You can still see the (grey) shape of the pond on google maps, satellite view, it is between the lakes and the crazy golf, and now has an oval track and bouncy castle.
Incidentally, my lifeboat would just go across the "track" area, but I usually put it on a short course across the bouncy castle bit.
