With the relative flat land in Wyoming or Utah, the horizon is far away. One side-effect of this is, that the sun goes down really low on the horizon – in contrast to the normally “high” sunset at home.
Also, due to the far visibility, the cloud pattern can be observed over a long distances. And one can easily be in full sunlight but observe a thunderstorm some 20 or 30 miles further down the road. This often results in very nice sceneries.
Being able to observe a rainbow is though as rare as at home. But this particular one, was very bright and really nice. Though I have to admit, I cannot share the same passion as the “Double Rainbow Guy“. Check out his video if you wanna know what I mean.
