For anyone interested, I have compiled a list of Twitter users who will be participating in the Potter Watch going on over the next couple weeks so people know who to follow and who will be there with them. If any of you are interested in participating, just give @getreadytoride a mention on Twitter, post here when you'll be in the park (I'm going by Morning/Afternoon/Evening to make things easier to follow), and I'll get you on the list. I'll try to keep it as up to date as possible.
Please be day-specific. If you post the day you're at the park, I won't have a chance to add you to the list.
Hope this list helps everyone!
