When I was in High School our JV went and played at Strasburg against their varsity. The floor had a center line but then on each side they had another line which was used for over and back. You had to get across the center line in 10 seconds but then you could go back to the other line so you had room to run your offense. The free throw arch cut through the center circle. They were not used when we played but they had lines on the wall of one side that were about 3 feet high....apparently they used to be the out of bounds lines, so if the ball hit below the line it was still in play.
Most if not all of the fans were in a balcony overlooking the floor(they might have had 2-3 rows of bleachers on one side). I think they were ranked in the top 10 that year(Lost to Steele-Dawson to get to state i think) and their fans did not care that it was the Bismarck JV(it was Bismarck High as far as they were concerned). It didn't help that the guys on our team put on a dunk show in warmups and I don't think they had anyone who could dunk. They had 2-3 really good players who I knew from Basketball Camps and some "farmstrong" kids who were pretty physical. game was back and forth and we definitely did not get a favorable whistle as I think we had 4 guys foul out and we shot 6 or 8 free throws compared to their 35-40. At the end of the game, we did get a gift call which the crowd went crazy over and we snuck out with a 2 or 4 point win. Pretty crazy atmosphere and after the game as guys were getting ready to shower our coach came in and said, skip the showers, grab your !@#$ and lets get going. They had a few fans who let us know what they thought of us on the way to the bus.
