If you can get away, I highly recommend lunch time running. It's great therapy and a nice break in the day. Also the best time to run in these parts.
It's pretty easy on a day like this when I'm writing all day. Not so easy when I'm balancing two or three time critical experiments at once! Really enjoyed today though, beautiful. Nice to get some proper sunshine, even in the freezing cold.
Something nice about sunshine, esp in the cold.
