You know you're in Montana when: the Interstate exit ramp has a cattle guard imbedded just before the stop sign.
For the unfamiliar, cattle guards are often located at critical roadway junctures amidst wide open grazing lands. Click here for slightly more information.
Please note: Today's photo is not that particular cattle guard - nor is it our Interstate.
This cloudscape brought to mind a snatch of song:
"Clouds are round about You, Shadows veil Your eyes..."
