If you want to know what "sinking feeling" really means, try driving into a patch of deep mud. Suddenly it feels like your wheels have been dipped in glue, the steering stops working, your vehicle starts to settle and speed falls off. Before you know it you're stopped. And stuck. If you go off road in wet weather you're going to have this experience sooner or later, so you need to be prepared for it. Part of that is having the right gear to get yourself out; you also need to know what to do. Trial and error is not the way to go when you have a couple of tons of vehicle up to its axles in mud. We thought we'd put together a few tips to help you out.
