Quick-chill beverages. If you live in a snowy climate, you could simply stick soft drinks, beer and wine into a snowbank (hey, it works). But for those in warmer zones, here’s how to get drinks frosty on the double: Fill a sink, cooler or other large vessel with ice and cold water, then mix in about half a cup of rock salt or other coarse salt. Submerge the cans and bottles for 20 minutes or so, then plunge them into a waiting tub of ice. You’re good to go!Borrow furniture. Need extra chairs or folding tables? Put out the word. Friends and neighbors will more than likely be glad to come to your rescue. If all else fails, remember that limited seating encourages guests to mingle, and coffee table picnics can help to loosen up a family meal.
