What limits do MLB stadiums put on the size of camera and lens a fan can bring to a game, particularly Yankee Stadium and Citi Field? Would they allow me to carry a Canon XTi w/ 80-200 f/2.8 and a 300 f/4 in the pocket of a photographers vest? The photo vest is not low key but I don't know how else to carry an extra lens. I think the stadiums disallow bags and backpacks. Are monopods allowed in the stands? What about the use of hot shoe flashes from front row or near-front row infield field level seats? Any other gear allowance or restrictions for regular seated fans? This is about shooting for personal use of course, nothing for commercial or media.
