You know, I did that program in Northern Virginia and you know that was the time when I was up there, I would drive up there, I taught two classes up there each week. I would drive up there on Monday morning and teach Monday night, you know, six hours, [laughs] two different classes. And then I'd stay there that night in case anybody had office hours or something like that. And then we also had associated with that the GAN program out of Virginia State. And I can't, I won't be able to give the official title for that, but primarily it was for underrepresented people to be able to get Master's degrees in mathematics. So we had this group at Virginia State. So I started teaching the classes in Northern Virginia by electronic stuff. And so I would usually leave Northern Virginia and I'd stop by Virginia State to talk to the students there. And then sometimes we'd have some students in Blacksburg too - one or two. And so then when I got to Blacksburg, I'd talk to them. So it  was kind of a circle of every week [laughs] making that trip that got old. But again, you know, the sacrifice that was made was well worth it. I had a lot of people from those industries in that class, and then Joe Guerci was a part of it that ended up giving us a large DARPA contract. So, it was great. I was on the Commission of  Research and I did a share of that commission one year, and everything went really well. And it was Lynn Peters and, uh, and Erv Blythe that came to me and said they'd like for, uh, you know me to take over the head of the research computing department at Virginia Tech. And so when I left Northern Virginia, I didn't go back into the classroom here.
