How can it save gas money if all four teams will play on two different nights? I can see having all the girls riding one bus one night and all the boys riding the bus the next night. Maybe there has been some hanky panky going on and the coaches and decided they have had enough. It would be a bad scene for the school if some young players cries sexual miscondut going on on the bus.
This is probably better for both teams, parents and coaches. It might also draw more parents out for the JV teams.

We had some young jv player mooning the car behind us last year!!! Had to sit out a few games.
