Ah . . . Springtime in Montana! Along with the warmth of the sun, you'll find birds and geocachers and such out and about doing their thing. . .
This micro cache could be a park-n-grab, or it could take you a while -- it all depends on the toughness of your skin, the sharpness of your eyesight, & some general good luck. This cache was meant to hide from muggle eyes. The hint takes half a star off the difficulty.
You're looking for something almost, but not quite, natural looking. The container is kind of delicate, so please handle and close it carefully and replace it with a thought to security. Log only, there is no room for swag.
Finding & rehiding the cache will have you out of the full view of muggles in this very busy area, but you will still need stealth.
