Based on intelligence obtained from a Forest Service special agent, a marijuana patch was discovered on USFS property adjacent to the park last September. A surveillance operation was conducted and two men were seen accessing and entering the patch from the parkway. The pair harvested 3,800 plants totaling more than 450 pounds. They were arrested after they loaded their vehicle and were about to leave the area. The two men â Mitchell Graska and Justin Saldivar â were found to be involved in a marijuana drug trafficking organization operating in Tennessee, Texas, Kentucky, North Carolina, Nevada, Nebraska, and California.
