[Koha] looking for a library in or near Durham NC

Hi, I represent a charter Middle & High school that is setting up a new media center in Durham. I am fortunate to have a volunteer LIS graduate helping me out. We would love to find a library we could visit that is using Koha to see if it is right for us. I know there are demos on the community website, but they just aren't the same as in-person :-) thanks if you are near and willing!! Alicia
