One of the reasons I have always liked March is the delicious minty green Shamrock Shakes at McDonald's. And now there is another reason to like them. From now through March 17, when you purchase a Shamrock Shake, 36 cents of the purchase price goes to Ronald McDonald House Charities. Ronald McDonald houses help families with seriously ill children across the country. So suck it up! Head to your area McDonald's get a Shamrock Shake and help a charity.
