When my old neighbor moved to Colorado, Woodland Park area, he built a new home in in the mountains and asked me to come out and wire it for him. He was a very close friend so how could I refuse. Anyway while I was there they got a load of graupel dropped on them and that was in mid august. At 9000 feet things are different especially for a flat lander like myself. Now let’s talk about how tough it was for me working at 7000+ feet when I’m used to 1000. It kicked my butt, and as expected about time I finished, 10 days or so started to acclimate. Paul
