When I arrived in Pueblo Colorado, the sun was shining and it was pretty warm.  After our second day of testing, the weather had turned a bit and, as we headed back to the town, there was some storm activity over the Front Range.  The road you drive out on is a federal facility so stopping to take pictures is not the best plan.  However, once we got back to the more populated area, I did pull over and take a few shots.  That night, there were some serious storms around us.  I saw a few over the mountains as we drove but nothing too dramatic.
