I'm trying to find the best camera support that I could get into a pro ballgame without a hassle. What I'd like would be a really small tripod with a long vertical exension. By small tripod, I mean the feet would be maybe 18-24" across. The vertical extension would be at my eye level when I'm sitting, so maybe 4 feet off the ground. If it were designed for just this, it would be really compact and wouldn't bother people in adjacent seats, but would be more stable than a monopod. Does it exist? Thanks for any tips.
