Two Tracked Argo HDI's and a MaxIV at the Big Nasty ATV park June 14th 2014. Since I have another tracked Argo with me I ran into the worse mud conditions I could find, in all the years I have been running AATV's and ATV's I don't believe I have ever seen mud conditions as bad as these. Even I was surprised that the Argo's could move in some of the sticky swamp mud with very little water.
