ahhh I bet you never lived in a small town
I'd go exploring, get to know the city. They say you can live somewhere and never see the sights. Go see the sights. When I was in Calgary the first time I went to COP, the Calgary Tower, say basically NONE of the downtown despite wanting to (just not time and it was Fataing FATA FATA FATATING cold!)
Then again being from a small place I am amazed by big building, and watching a big city operate, people moving, walking, how the traffic goes, the culture, non-verbal reactions of people etc.
or
drink and watch TV, go on the computer (take something normal add drinking, always mades for a good time)
