The way 'Big Brother' is slinging regulations and laws at us, we sure as heck don't need spectator sports to have their heavy hand there too. Look at baseball - and Senate hearings with the use of steroids - it's none of their damn business if Roger Clements or others used them. Go to a doctor's office and read that Hipaa form. Even your wife/partner can't get any information. Then Obamacare - and the regulations go on and on and on.
Dam' ya got me started.
If you don't want to spectate, as Dave S said, don't. It's a heluva lot more dangerous statistically wise driving to an event to be a spectator then being there. As a participant, your odds do go up. Heck, stay home, maybe even stay in bed with a pillow over your head. Oh and the odds of being hit by a piece of space junk now about to come down, 1 in 3200 (Defunct NASA satellite to crash to Earth this week | Reuters) so that pillow - wont help.
