this is the way i look at it if baseketball is your "sport" do you do overtime at work to pay for extra baseketbal's, go on the net to learn how to build net's, then work in the garage making net's, think about the court all day, when you talk on the phone you talk about baseketball and would you sell your soul to buy a ski woops! i mean pair of nike's to do a backflip dunk???
sorry about all the ball talk
this was always a issue in the stunting world too people would always say stunting is not a sport but how many ways can you twist a throttle and go around a track?
