Sorry I missed you too! I had to teach two classes Friday, so I was in for a good chunk of Thursday to help with setup and then had to drive back. I didn't get back to Planet on Friday until about 5.
Fridays are usually a good day to shop for books at any show. I thought the crowd was decent for Friday and pretty strong on Saturday. I can't compare to past Planets as this was my first, but compared to other shows I thought they did a fine job of getting people in the door. Especially considering the awful weather and generally poor parking options around the convention center (off topic, but who builds a convention center of that size without even a small parking garage?).
The dealer you mentioned with the strong sales, assuming it is the guy I'm thinking of, got some strong dealer money and sold some big books on Friday. They were not getting any better walkup sales at the table than the rest of the booths were. The money still spends, of course, but that outlier should be put into perspective in terms of the strength of comic sales at the show.
