Whoopie for them, they have doubled their first estimate. They could get many more through but they don't seem to be doing that. Wish I knew whether that is by design. The people on this thing are very used to going through searches and don't take forever. The restrictions are not as strict as they were at the Library.
It is a very wet 84 out there right now!. Steamy as a Louisiana bayou. People will be waiting all night. It's likely nice to get into the cool building.
I haven't been watching C-Span so I don't have a feel for the pace of the crowd but they may be having a late night lull, or shift changes, etc. I'm well familiar with the steamy heat of a Louisiana bayou :) and that may have something to do with it, too. LOL.
