In this recession era of belt-tightening, nothing sounds sweeter than the word free. The new West Palm Beach Public Library, barely a year old, has taken its mission of providing free services to heart, so much that books seem almost an afterthought. On Saturday mornings, hordes of people ride the elevators to the third floor, where sunshine pours through generous windows to illuminate gleaming hardwood floors. In a carpeted auditorium, a free yoga class is taught cheerfully to children and gray-haired yogis alike. Other days, one can find free Pilates and tai chi classes and perhaps an Argentine tango performance. Here, seniors or the otherwise technologically impaired can learn to navigate Craigslist and PowerPoint â hell, even Wii Bowling! So go to the library, and take your Bubbe with you. She will be so proud.
