Well that seems kind of funny...

After a couple of hours of discussion in the phillyd forum, the following observations have been shared:

THE HOPSCOTCH VIDEO
In the "security" footage, the time stamps do not follow in a continual manner; instead of progressing from 12 minutes to 13 minutes then to 14, the time stamp jumps around, starting at 25 minutes then skipping back to 4 minutes at one point, and ends with 1: 40 approximately.

I have not yet recorded the entire time stamps, but I will be back with screen caps later on.

The scavenger hunters think it means we need to interpret the data in that video in a particular order; it may apply to the number letter combinations that appear at the top of the screen.

If this is true than instead of "7F 1A 9S 6J 3W 8Q", the new order would be "1A 6J 7F (7F) 9S 3W 8Q"

THE CALENDAR
Also, hunters noticed early on that the date for January 12 brought up the itinerary for January 25 (the year 2008 for some reason). But as someone pointed out, all of the dates for January are screwed up save for January 5.

What this means has yet to be known.

HIDDEN MESSAGE?
Probably nothing, but still worth noting. One of the images has very faint, gray writing that can only be observed if the image is manipulated. The screen shots below point it out.

It's possible that the white box is actually representative of an x-box, and that the writing is irrelevant to the whole hunt, so hunters aren't worrying about it too much.

That's all for now!
