Ok, here's a long writeup geared toward auto-hunting with the huge caveat that I've only actually collected a few autographs at past conventions, so I really don't know what I'm talking about. This is the way they've done things the past few years -- who knows if it will be the same this year. When you arrive, you go downstairs to register and get your packet with the schedule, etc (if you're staying at the hotel, ask when you check in about the registration materials). The packet will include lottery tickets for auto sessions for players in high demand (Maddux, Prior and Wood have been recent lottery tickets). Fill 'em out, turn 'em in and they'll post the winners at some announced time. I've heard that if you *really really* want a winning lottery ticket, you can hang out where they post the winners and scalp one. They have autograph signings and picture booths located in a downstairs ballroom. There will be schedule of who's where when in the convention packet. Be forewarned that lots of people go only to collect autographs and the lines are not all that well organized, so it can be a zoo. Again, if you really want someone's autograph or picture, be prepared to get there very early and spend a lot of time in line. The storefront booths are located in another downstairs ballroom and it's worth wandering through to see everything that's for sale. You can find plenty of stuff to have signed there. They do have an auction for new and game-used jerseys, etc; just ask around if you don't see a sign for it. There's also a silent auction for 7th inning stretch singer stuff in the registration room, and look around/ask around for any other lotteries/auctions that are going on there. If you attend the sessions, often players and others will sign during the breaks (the sessions that are broadcast have radio breaks). They'll let you know when it's ok to ask and when to sit down. They've emphasized past teams in 20-year cycles, so expect to see some 1986 Cubs wandering around. sidenote: just realized that 1986 team (70-90) will have had 3 Hall-of-Famers -- Eckersley, Sandberg and Maddux -- as well as Rafael Palmeiro (hmmm...). Jon already thunderstruck my advice on the sessions. :) They usually put the audio files of the broadcast portions of the convention on the WGN radio website after the convention, so you can always choose to go to a non-broadcast session and listen to the other sessions later.
