What is mud drag racing

One thing that mud racing is not, is boring. Before I had ever seen a mud drag race I had pre-judged and thought I wouldn't like it and it would be boring. In 2009 I started helping a friend of mine who races a mud racer and after my first night of watching the mud drags, I was hooked. To be honest, I never thought of mud racing as something I'd be interested in, as I'm not a big fan of 1/4 mile
