I agree, but sometimes I want a tripod just to hold the camera off the ground, so I fold the legs of my tripod & loosen up the head which works well for me.
I have no idea how it's around your place, but on most of sport events around Europe, tripods are not allowed on sidelines or on track.
It still wouldn't go through with most of security people around here though. On some events (skiing for example) I understand tripods are banned, since it can actually be dangerous. On others, I really don't understand why it is like it is, but... we can't do much about it, if we like it or not
