Build and maintain libraries with the money we spend on pro sports
Support youth sports
Watch a kids game or event that you aren't that familiar with - debate team, girls soccer, drum and bugle corp, dance competitions, drama club, etc.
Find another sport to enjoy that deserves the respect and support of the fans. I like boxing.
Watch women's sports - soccer, WNBA, etc. They aren't rich, there are some special athletes and they appear to be trying to win!
Buy books and teach kids to read every Sunday afternoon from 1-4 p.m.
Spend your money on businesses that treasure their customers
I gave up watching baseball after the strike in the 80's after being an Indian fan for all those terrible years. I lived. I don't waste any time watching pro baseball or wondering which of the stars have been juicing. It shouldn't be hard to give up the NFL.
