Bali...Bali he says. Why don't you and Jo come to the great white north and try some.... ice fishing. Yep doesn't that sound like fun???? Snowmobiling....downhill skiing, snowshoeing....brrrrrr

Or, given your sailing prowness, you could try some sailing on the ice. But Bali....that's no different from where you currently live.
