I compete with other posts on this forum. Therefore, posting is a sport //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gifsport is considered competition against others. If you bowl in a league, tournament or other sanctioned body you are competing. Therefore bowling IS in fact a SPORT !!
Now if you go bowling once in a while with your buddies and just drink and raise hell and piss off the owner of the bowling alley. I would consider that kind NOT to be a sport.
I guess it would just depend on the situation. I personally gave up on that stupid game.
