Crazy carpet:
http://uk.youtube.com/watch?v=cow6l8IJWuA&feature=relatedSort of a thick nylon sheet 4 feet by two feet with two holes in the for handles. You sit cross legged on it and hold the handles.
If your darring you lay on your belly.
You slide down a snowy hill, you slide like hell with no control.
If you don't have one card board will also work, better if you spray it with silicon.
Infact anything goes better down hill with silicone on it........
Tyre tubes also work well and the traditional wooden 5 seater tobogan is also a must to try once in your life. Adults must ride down hill and or skate at least a few time, sitting next to the fire all night telling BS stories is frown upon
For maximum effect bring hot dogs, rum and or brandy, hot apple cider, marsh mellow, make a fire, invite as many kids and parrents as you can find and slide untill bed time.
Best location frighteningly steep hill near a lake so you can skate bewteen runs. Better still if lake has fish to punch some holes and set up some jigs. Lake trout should be fried ASAP, White fish smoked on site, brown beans and potato salad recommended to go with the previously mentioned fish.
Other considerations:
Sauna ( where facilities exist ) and the adults whip each other with a vihta and don't forget a roll in the snow or polar bear dip to be followed by a warm brandy at the camp fire.
If you follow these directions carefuly you can enjoy winter parties the Canadian way.
If its spring or late fall check the ice first and be safe.
