So after living for 20 yrs 2 mi from the levee along the east side of the everglades, tonight I did the ride from Markham Park to Atlantic and back. It was quite a different ride from my usual road rides. The levee is gravel and broken pavement, and at 15 mph it is pretty jaring, even with front shocks on a MTB. I started out with the A group but got dropped after about 2 miles. Did the next 8 mi solo. Got to the turn around at Atlantic and the A group was there. We waited on the rest of the riders, and headed back. Again I dropped quickly from the lead group, but drafted a few for a couple of miles. When the faded I pulled into the lead but they couldn't hang on. It was fun, but quite a "white knucke" ride. The levee is about 20 feet above the swamps with a steep drop on either side .
