cooling wort outside

im getting ready to boil my 3rd batch of beer, its a Brewers Best Weizenbier kit that i got from the LHBS that im going to add cherry flavoring to to make a cherry wheat beer, and i was wondering, since its like 12 degrees outside and i dont have a wort chiller or much ice on hand, would it probably be best to just set the hot wort outside to cool down? and if i do could i leave the lid set a little bit to the side so it will cool faster, or will this let contams into my wort?

This is a discussion on the lower part of this forum's page 1

Leaving it outside will cool it down, tho very slowly, and its not really worth doing.

Instead, you would be much better off to fill your sink/bathtub up with cold water and ice and let your covered pot cool in the water. Water is much better at transferring heat than air/snow. However, if you still want to cool the wort outside, find a big tub, fill it with cold water, then put your covered pot in the cold water and move the whole thing outside or into a snowbank. Works great.
