Find good hometown family fun, all for a good cause at ''Happy Days on Merkley.'' The day long, fun for all ages event features a classic car show, live music and entertainment. Show off your hidden talents with a variety of competitions – pie baking (and of course pie eating) contests, hula hoop and bubble gum blowing contests. The region's next American Idol might be discovered in the Elvis and Grease singing contests…or If You Think You Can Dance you might want to crank up the jukebox and sign up for the hand jive or twist dance contests. After working up an appetite, step up to the old-fashioned soda fountain with soda pop and hot dogs at old-fashioned prices. The evening caps off with a BBQ dinner (additional charge) and classic sock hop dance. Admission is $30.00 per family of 4 or more; $10.00 for individuals; children 5 & under are free.
