This should be an easy find but then again that's only because I know where it is. Mobile Fence seems to have a lot of chain link fences "around" Mobile don't they? The cache relies strictly on links and an iron support to keep it in place. If you look in the wrong place for too long your energy and battery levels could become drained.
Congratulations to Heavy505 for FTF!
