My "home court" when I played growing up was the local Community Center with a very small gym.
Absolutely no room around the court for throw-ins as the folding chairs for the benches and spectators were right along the court. Many a time diving for the ball ended up in major collisions with spectators and heaps of mangled chairs. It also had a balcony which made throw-ins difficult for the taller players (not a problem I had).
I remember the main, double-doors for the gym were right under the one basket located very close to the court. If you ran too fast for a layup on occasion you would go right out the doors – and if they weren’t open……..
Ah, the good/bad ole days.
