My local club the King Crawlers has been working with our county to build a 4X4 challenge park. We have the land laid out, the comissioners convinced it would be good for the county, several course we want to build, heck we even have the national guard willing to build it. The best and worst part is that we get to design it all. The county is asking for specs on the events to help protect them in the case of a law suit. We are having a hard time finding any thing that looks some what offical for the to put in their files because lets face it there is no right/wrong way to build these things, the varity is half the fun. But we stll need specs for; mud bogs, hill climbs, tractor pulls, teeter totters, RTI ramps, log cross, wash/tank traps, rock gardens, obstical courses, car crush, or new ideas. Thanks in advance.
