It was difficult to get sites added at ICO until this last year. We had the same problem of having to many sites and not enough students. Over the last year they dropped a lot of sites that were sub par and are now adding new ones in places of interest. There are about 15 students in my class from Wisconsin and we had no sites after they cut the one we did have. So it was actually very easy from me to set up two new sites for the school and I will be the first student to go through them. In a way that will be great, b/c they will have no bar to compare me.
In a nut shell, I think we are all saying it depends on the school and if they need more sites.
