Well all you riders that have been bitching there's nowhere to ride in Miami....I found the place...Coral Gables. On the weekend the traffic is light. Speed limit is enforced at 30 miles an hour.
You have all kinds of places to explore. If you want something to eat or drink you have Starbucks and a host of other cafes and restaurants. Go north on ponce de leon head west on Alhambra this will eventually turn into a bike path. Once your on the path if you turn on one of the streets heading south you should run into a Golf course that has a nice road that winds around it. A good place to practice some sprints. Then you can explore all the back street through the neighborhoods virtually traffic free. Once you're done you can head south on Ponce till it ends at U.S1
here you can catch the bike path under the metro going North or South or you can take the Metro Rail. I rode here Sunday and had a blast.
