Summer can’t be all fun and games — or can it? No need to float a loan for trips to the water park. All you need is a back yard or patio and a handful of classic pastimes to while away the lazy hours. Start by investing in the basics: a croquet set, ring-toss game and oversized outdoor playing cards. Blow some old-fashioned bubbles with a new scent like ice cream (equally popular with kids, grownups and dogs). Come sundown, relive the childhood magic of catching fireflies in glass jars, then releasing them again. Even prizes and party favors can be easy: think cookies, candy or rainbow blobs. And when the day is done, gather everything up neatly in big woven bags for easy storage. You’ve had a great time and created memories, no batteries (or big bucks) required.
