That looks so ***king exciting!!! How much have you spent in this hobby so far, and also where are you from? I'd love to get into that sport, but I don't have any means of transport from my parents (well my dad, but I only see him on a weekend). I also don't think i'll have enough money and my mam will complain, i've already got 3 hobbies, I don't need more, lol! My hobbies are fishkeeping, karate (it's getting very boring now) and boxing (i've only been twice).
I'd try it in my truck, except there dosen't seem to be anything solid around to connect the winch to. I wish I had a mudhole that good around.
