The Red Rocks Amphitheater in the foothills west of Denver is a neat place. While I never went there for a concert when I lived in the are in the late 90’s, I went there often enough to hike around and test liquid biprop rocket engines in the parking lot when security wasn’t looking (what, was I going to test them in town? Don’t be silly). Along with concerts, something else I never experienced there was a hailstorm. Having seen the videos from last night, I’m just as glad that I missed out on that.
