Why do my parent's have to live on Hill Street?!?

I was able to fit in a run Christmas morning (which was great because I didn't feel nearly as bad stuffing my face with all that food later in the day). I did 6.25 mile run around their house, which was supposed to be an easy run, except that my parents road is named "Hill" street for a reason - a Hill that they live right on top of. Holy hill workout! It was good because the marathon course has a lot of hills, but not quite the leisurely Christmas run I was expecting.
