Hi SUPlove,
Welcome to TE. I live in Miami and am usually found at Key Biscayne on the weekends. It is a very cycling friendly area. Take a look at the Everglades Bike club site and Broward Wheelers. They are two great cycling clubs. EBC is hosting a century ride on March 28, 2010, in the redlands, south dade. It is a great supported ride and will get about 2,000 riders. Let me know when you get your new steed.
