We live just south of the Retired Monkey Challenge Trail, and this past winter was very wet. We have gotten some of the caches for which we qualify, and the ditches were still holding some water. Our biggest obstacle though, as an approximately 8 foot long Cotton Mouth water moccasin. This is Florida. It would not be unusual to see venomous snakes, including moccasin and Eastern Diamondback Rattlesnakes, as well as many other dangers, including protruding roots/branches from trees and bushes, broken glass, rusty metal, the affore mentioned fireant hills, poisonous plants, and the list goes on. My suggestion would be to bring an old pair of shoes you can just throw away after completing the series. Good luck to you!
