It doesn't take a lot to keep me entertained. I always have fun going out to bars on the weekends, but I could just as easily stay in and have a good time.
I try to stay active. I ran track and cross country in high school and college. When grad school is not taking up all my time I run as much as I can. I do a few road races here and there. I want to get more into it though, I love competing. If I could find time to really train hard I would love to get back on the track and do some mile and half mile races too.
