It turns out the right turn buckle and unscrewed a few rounds. Bill showed me how to fix it and we were able to dismount DIS. Not that it really mattered, in the end. The night started out with clouds with virga and radar pings. However, it didn't start raining until around 10pm. Things cleared up suddenly a little before 4am and we were able to open! And to good seeing! The OU class completed their second night (admittedly with a little less energy) and are gonna be pros by tomorrow!
