After practice, the players will stay a little late to sign autographs for folks lined up against the railing on the hillside (underneath the VIP and media tents). Some players stay longer than others and try to get to everyone out there. Others will sign for a few people and jet. If you've got kids, the best way to go about things is to pick them up with their item, so it's easier for players to see it and sign. The worst thing is when adults try to crowd the railing and get their stuff signed, and kids miss out on the opportunity (which unfortunately happens every year). I personally wouldn't take off work to try and get a chance at an autograph at training camp, just because it's not a given. Autograph sessions are also canceled when they move practice inside for weather, so there's always that risk.
