Throw a Stick of Sage into the Firepit/Bonfire. The sage scented smoke that the fire will emit keeps mosquitos and other annoying bugs at bay for the entire area. Usually the sage stick is enough, no need for bug sprays.
Awesome idea for a large summer cookout or at the beach with family. Put shucked corn in a cooler. Pour boiling water over corn then close the cooler. In about 30 minutes you have perfectly cooked corn.
