My schedule (5:00 - 2:00) works perfect for officiating basketball in the winter, coaching high school baseball in the spring and golf in the fall. I can do a 3:30 Jr high game and still have time get to a 6:00 JV or a 7:30 Varsity game. In the spring and fall I can easily get to after school practices and games / matches.
The only drawback is that damn 4:00 am wakeup call.
