BOISE COUNTY, Idaho (KTVB) -- A massive keg party just off Bogus Basin Road could lead to charges against dozens of Boise teens. Boise County Sheriff Ben Roeber says it happened Saturday night on Boise National Forest land. That's where officers found about 100 teens, most involved in underage drinking. Roeber tells KTVB the teens were partying near milepost 12, about a mile off Bogus Basin Road. That's where officers found trash, several campfires, beer, liquor, and drugs -- marijuana and ecstasy. They also found several teens sick and unconscious, some who needed immediate medical attention. The Boise County Sheriff's Office, Ada County Sheriff's Office, Ada County Paramedics, Idaho State Police, and U.S. Forest Service all responded to the scene. The Ada County Sheriff's Office says a hunter noticed the large amount of vehicles around 11 p.m. Saturday.
