Tis the season...of the Shamrock Shake! I usually don't endorse eating at Mickey D's, but Shamrock Shakes rule. I'm enjoying one right now, as a matter of fact. I had no problem finding the minty green milky goodness at the first Mcdonald's I tried in Minneapolis today. But I guess it isn't so easy in other parts of the U.S., as evidenced by this site.
