After leaving the Black Hills we drove across the rolling grasslands of south eastern Wyoming. It was a hot day and thunderstorms started popping up all around. As we neared a storm the wind would suddenly gust in the direction of the dark clouds, as if the storm was taking a giant breath of air, then calm again after it passed. Finally tired of driving we pulled off the highway and parked along a gravel road for the night. We spent the evening watching lighting storms pass in all directions, the show became even more impressive after nightfall.
