I enjoy the hunt for the shot. I really don't do much with them, occasionally I post here, I have a website (zenfolio) and facebook, both of which get few visitors. But the main the main thrill for me is the shot. Even if no one ever see's it.
I can imagine going to a HS sporting event and trying to get one of those sweet shots you all sometimes post. A long jumper in flight, a football player making a catch, etc. But my kids are in elementary school. Is it wrong to go to a HS sporting event as a spectator and try to take (non-professional/not for sale) photos of the event?
College does not give me the same "Do people think I am creepy" feeling, however I am much more limited in my opportunities to shoot college sports. I have not shot HS sports before, but think it would be an interesting experience... if its appropriate.
Me personally, I don't care who takes pictures of my kids. I don't understand the issues that many other people have along those lines, but I respect that some people do have an issue with it.
