Estero/Marco Century

Ride the loop at the top and then down to Marco Island and back to get a full century in with some challenging headwinds and a pretty tough bridge to get onto or off of Marco Island.  :)  Livingston/Imperial/Three Oaks is a great road with bike lines all the way except for a few miles at the southern end of Livingston, but there is plenty of space for cars to pass you in.
