I remember owning a power washer that I bought at Harbor Freight, home of cheap tools, a long time ago. I brought it to my parents house to help clean the siding and immediately blew a chunk right out of the side of the house. Oops!
Here is a video of my Cat 4 race unedited. I gives a pretty good look at the whole course and all the obstacles you face on a muddy day like this was. I apologize in advance for the cussing and swearing and such.
