The weather in South Florida is as extreme as it is unpredictable. Some days, it seems as hot as the surface of Venus. Other days, it's raining so hard that you'd think the ground would never lose its thirst. That spells trouble for local athletes. But there's a solution: Sports Mall. This 75,000-square-foot indoor sports complex in Deerfield Beach offers soccer and roller hockey leagues for children and adults. Adult leagues also include basketball, with young whippersnappers and players old enough to be their grandparents. But Sports Mall offers more than competition. It's also a damned fine place to grab a drink. Set in an island between the soccer and hockey fields is a bar serving beer and sports drinks. If you're not the athletic type, buy yourself a draft and have a seat next to one of the fields. You might be lucky enough to watch a face pancaked against plexiglass inches from your beer.
