Kids will love an outing to Cypress Point Park on Tampa Bay Florida. It's right in the approach path to Tampa International Airport and the planes fly quite low and directly over this park. It's a great picnic venue with built-in entertainment, plus it's on the water in a fairly quiet area (if you don't count the jet engine noise).
Another in my series of what to do with out-of-town visitors near Tampa Bay, Florida. In Christmas, FL, Jungle Adventures is a little farther afield than most of my destinations, but well worth a visit. Live gators, panthers, peacocks, tortoises - you name it. The staff is enthusiastic and the building is unforgettable.
