There is an "open version" of the game which is popular and can be played anywhere, but a regulation bocce court is 76 feet long and 10 feet wide. You must make sure that playing surface is flat and level (packed dirt, gravel or grass are ideal).
The game is a lot of fun and perfect for a day out in great weather. Finding a bocce ball set is pretty easy. There are plenty of online store that sell them and even local stores in the mall or sporting good stores. For more information about bocce ball, check out http://www.bocceballsets.net/.
