College students have finals. A couple people have been saying that "they could take the week off from school", but it's not that simple, guys. These are FINALS. These students work for the whole year to make sure they pass this thing. They cannot simply take the week off. It would probably be a real hassle to setup an alternative finals date and they might get docked a grade.
A lot of workers won't be able to get the time to take work off. People on the west coast, if we go by bus, would have to take 9 or 10 days off work. That is not merely saying they're sick. That's probably half the frickin' rent! That's insane!
Like Utah pointed out, some people are waiting to use their rebate check to go. Rebate checks aren't going to arrive by April 15th. So there's a bunch of people out.
It's real short notice. How the Granny Warriors are going to get the permit and secure a location by the 15th, I don't know. They'd have to apply for the permit right now. In a topic it was said they have the permit in hand. But I don't believe it until I see it.
"As an event planner, you are required to meet with the Special Events Task Group at least 60 days prior to your proposed event. Due to the large number of events held in Washington, DC, and the District's extensive regulations that govern event planning, you should contact the Task Force at least 120 days in advance of an event." -- Straight from the DC site.
