Forgot to mention: If you're going to Comic-Con International this week in San Diego, two downloads may help you a lot. The Comic-Con App is free and packed with loads of info. You should also download or at least read the Comic-Con International Quick Guide, which will tell you what's where and when and why and who's on first and what's on second and answer many of your questions.
The Quick Guide will also give you a piece of information you might want to know: The 2017 Comic-Con will be July 20-23 with Preview Night on July 19. If you're going to need a parking space down there, now would be a good time to start looking. (Hey, I haven't used that joke in years…)
Also, there's a lot of info on the con over at a site I've recommended here before called The San Diego Comic-Con Unofficial Blog. It has no affiliation with the con itself but still manages to gather a lot of good info and tips. I probably shouldn't like this site because they show a pretty blatant disinterest in any event that doesn't feature big movie stars or big TV stars…or worse, is only about comic books. But they're enthusiastic and they work hard and they really provide a useful service. Plus, I have hopes that after I host my 500th panel and/or am a Special Guest of the convention for the thirtieth time, someone on their podcasts will learn how to pronounce my name.
