I'm currently finishing up this summer's lab work. This upcoming Saturday I move back into the dorms at Ohio University and start classes on that Monday. I plan on trying to get out one or two more posts this week since I have a few days of "rest" before dealing with the craziness of moving in and starting classes. Thanks for reading!
