Awakenings: Splish Splash or Shake It Up...maybe both! Load up on ice cream! With June being National Dairy Month, this summer favorite frozen treat (usually made from dairy products), is on the calendar twice in one day. Start first with a "Splish, Splash" from the 50s to set the mood. Then, get ready to shake it up, baby! June 20 is...National Ice Cream Soda Day & National Vanilla Milkshake Day!
