Remote Control Truck Pulling What do You Think?

Here is a good assortment of truck pulling with the weighted sled I think it is very interesting to watch these tractor pulls as they call it. I was just wondering why there are not more of these it seems like these machines are built for the craziest low end power and when they take off they scream. Well just wondering how big of audience really does these truck pulls.

There are ton of videos on Youtube if you want to watch them but I thought this one was pretty good. I like the one with the jet engine even though I thought it would perform a little better it was a cool thin to watch.
