I did a google search and there really is a drink called

BEACH BLANKET BINGO

Equal parts of Cranberry & Grapefruit juice, Splash of Soda

Stir juices over ice in a Collins glass, top with soda, Garnish with a Lime wedge

Granted there's no booze in it but I think it would be very fitting for the younger one's attending the beach party or for those of us who are designated drivers.

Edited: just did another search and there really is a drink called "Beam me up Scotty". Damn it Jim I'm just an old country doctor, not an engineer!

Must get back to work now after swatting all those mosquitoes.
