 If you are having people on a drop-in basis that often, for the purposes of designing a budget for your grant, is that I think it's easier to kind of include more people than you originally had planned on because, generally speaking, the cost involved of, say, an extra five people is not, that's not the big cost in, say, putting on an event. Because of the way that the evaluation process has been set up, more it's hard to kind of determine, well, who, by, in the terms of the grant, is really a someone who's really a member of the grant as opposed to someone who's just dropped in. The good thing, though, about having a committed cadre of teachers is, are things like a spirit of core and really having people, especially if you're working with multiple schools, multiple districts, that sort of having people get to know each other, get to work with each other on projects from different schools. It's wonderful to see, say, suburban and urban school teachers working closely together and building those kind of connections. We'll do, like, a big summer away trip, say, to Washington, D.C., or we did one to Birmingham and Civil Rights Institute there. And in hindsight, I wish that we had done that at the very beginning as soon as possible because once they'd spent three days together, that group was so tight. And tight, they were comfortable talking about things, they were enthusiastic. It makes it possible to develop teaching modules or lesson plans or whatever it is, the kind of end product that you want these teachers to kind of develop as a result of this to be much more comprehensive. You've got the same group of people, so you can get them started early on in the year. You can set special events that are, say, just about, say, using technology and developing classroom resources or in keys to developing a successful lesson or any number of things. I guess there's always an opportunity, of course, if you can figure out how to finesse it to do a little of both. In other words, if you have, say, a committed core of 25 or 30 teachers, but you really could take more people, well, then why not? Every month we'll have what we call a history form, we'll invite an historian, we'll have a dinner, we'll have maybe some kind of workshop or something connected with that. And that will, of course, the teachers that are involved in the course come to, it's part of their class, but we'll open the doors and invite the entire, the people from all the districts that are being served. And so that is, there is a way to kind of do it both.
