Hmm who knew the Forest Service had drug sniffing dogs.
Check it out:

In late February, four federal agents carrying side arms with a drug-sniffing dog descended on the Taos Ski Valley in what was called a “saturation patrol.”

uthorities were working on tips of possible drug selling and impaired driving in the ski resort’s parking lot and surrounding area.

But the agents weren’t from the FBI, ATF, or even the Drug Enforcement Administration.

Rather, the agents represented the U.S. Forest Service.

“It’s one of the untold stories about government,” said former New Mexico Gov. Gary Johnson, who lives in Taos, is an avid skier and has been a leading critic of the operation that turned up only a few minor infractions. “People don’t grasp the size and the scope of these entities and their law enforcement arms.”
