This cache will not only be trickly to retrieve, but doing so could prove to be a bit risky. Especially if you don't want to get wet. The bison is in plain sight once you reach ground zero. To reach it, you will need some special equipment. Exactly what you will need to retrieve the cache, will depend on you and your skills. When you go after this one, I highly suggest that you not go alone. Especially if you can not swim, because there is some very deep water here, and the canal's banks are steep. Besides, having a second pair of hands, will come in handy. Once you have it, please be careful with the cache and it's parts, and carefully place it back where and how you found it, so others can enjoy the fun.
While you're out here, you may want to bring a camera. The area that this dirt road passes through, if full of all kinds of native wildlife. I've personally seen Bobcats, Eagles, Gators, various types of snakes and lots of birds. This canal is also full of fish.
