You know it is off season beacause you, as a programmer, are no longer thinking green. Even more important, camera problems are no longer being discussed on a daily basis. Capping the center of anything is only being discussed around the fire pits of American campgrounds and not really on these forums anymore. The season is now a legendary story that you can tell your friends, buddies, relatives, and anyone else.
In short, you can tell it is off season because FIRST robotics has gone into hibernation for the summer. Get the rest you want and need, and just enjoy the break.
