It's great that you guys are offering to help maintain these ranges. I was involved with the engineering of the range improvements and the new range constructions around the state. The local WMA Biologist would be the person to contact. They usually handle all activities at their assigned WMA. You can get his name and number from the ODWC website. If that doesn't work, I can privately give someone the name and number of the ODWC person who is coordinating all the range improvements and new construction.
