I went to that pull several years ago .. we showed up around 5 pm and paint driers were pulling .... they had been pulling since sometime early that morning ... then after the paint driers quit they went to non turbo diesel tractors ... then the standard tractor classes. They also had several gas 2wd and 4wd classes, a stock pickup class, a very small diesel truck class, and semis (which werent exciting at all). We finally left at 2 am and they were still pulling. So you could say "big" pull is an understatement. Lots and lots and lots of pulling but it is 100% a brush pull so dont expect to see anything crazy like what you would see at the "show-me show-down" in moberly.
