Have you ever been at an outside gathering of family and friends who drove over three hours to visit your house for a big bbq, just to have it start to rain? I have. Too many times. I keep packages of rain ponchos on hand for just such a case. I want my guests outside more than inside, especially if it's wet outside. If you put on one of these ponchos, it has a hood for your hair and covers pretty much all your clothes so it really minimizes wetness, keeps guests dry and lets the party continue until the weather blows over. Also good for stadiums and other outdoor events.
