I love a good list, and especially when it is about trails! The Florida Department of Environmental Protection has put out a great "Ten Trails You Must Experience" list - you'll likely recognize many of the places. It includes trails for equestrians, mountain bikers, paddlers, hikers, and rail-trails for road cyclists or for those looking for a relaxing ride through rural Florida.
This list comes just in time for the holiday season, too. I don't know about everyone else, but I imagine I'll be needing to refer to this list very soon. Go ahead and eat extra during the holidays, and work all of it off with DEP's trails list! Here's the link: http://bit.ly/ektKdw
