I had a GV Game last yr where they turned out the lights so they could do their HS version of the ole Chicago Bulls opening.......unfortunately, when they were finished with the festivities it took the lights a good 10-15 minutes to heat up and come back on.
The H coach asked me if we could start the game in the "semi-darkness" as I guess he knew the beat-down that was going to happen.
We waited......he was right!
