They went to see the Grand Canyon, and it was cloudy
The worst thing that can happen when traveling to visit the Grand Canyon in Colorado is for the weather to be cloudy. The main attraction is the giant, natural crack in the ground, and it is a serious pity to miss out on seeing it because due to heavy and thick cloud coverage.
We have to admit that all those clouds do make for a very cool picture, though. It may have been disappointing for this visitor to not have been able to see the canyon itself, but this tourist should definitely not consider the trip a waste.
