The local park.
The public beach.
Playing a board game at the dining room table.
The backyard (or frontyard).
Taking a drive an hour or so from home.
All of these places, and a whole lot more, are great places to entertain that won't bust your wallet. Cheap or free, in most cases.
Nobody ever said that entertainment has to cost an arm and a leg. Think outside of the box, if you find yourself living life on a shoestring budget and want a little bit of rest and relaxation.
