These new rules were made up and agreed upon by an committee with years of mud bogging experience and knowledge. A lot of time and effort was put into making these new rules as it was not an easy task. We understand that the new rules may affect some people more than others. If it has we are sorry and that certainly was not our intentions. Our intentions were to make the rules as fair as possible for everyone without compromising safety. We certainly don't want to leave anyone out. It may take some time, but we are hoping that everyone can adapt to the change. If everything goes well, we are hoping that these new rules will only make the competition better. If you have any questions, please contact any one of us below. We are all looking forward to seeing you this season.

Final Thought

Enjoy the season with this in mind. The Gumboro Mud bog is a family oriented, Christian based event. We ask that you be respectful and courteous of others. Please do not use foul language, dress modestly and refrain from bringing alcohol on the premise.

If found in violation of our Rules and Regulations you will be asked to leave the premise and will not be permitted to any further events for the remainder of the season.
