how to accomplish a rilly big ice amphitheatre in your own backyard, 2008

Our local outdoor ice rink had only 6 good days of skating all year last winter. Ive never made a skating rink before and our backyard is on a small hill, but i figured it would be good for my kids to be able to skate every day, and they could have friends over. So in late november, i decided to try to find out how to make a rink the easiest and cheapest way i could. I asked a canadian friend who told me how his dad just stomped down snow and watered it with the hose, building up layers of thin ice. I combined that with my observation of how long a big block of ice seemed to last (when you dump out a frozen bucket, etc), especially in the shade. Ive seen people build strong wooden frames and use water-tight liners, but some winters here things dont seem to freeze up like youd expect. Heres the project: im trying to find out the easiest and best way to make a thick block of ice for this climate: one that is flat and strong, and lasts a long time. I made it using boards as guides to build up the ice a little at a time (not to support 10 inches of water all at once). Its working really well and it hasnt been any trouble: weve just had a whole week (feb 21-28) of 30s and 40s, but the kids are still skating (except when its raining). The melting water just runs off the sides. I know some people with liners say they cant skate when its warm ( because of pooling water). Maybe next year i can find a way to combine both: use a liner to make 12 inches of ice easily, but then get ...
