Yup I don't drink, smoke or do drugs and always have a great time when I go out, be it local pub, bar or whatnot. I gotta agree with others but, going out with fantastic company can make or break the night.
When out partying sober you can still do what everyone else does, dance, mingle, mosh in the pit at as a pub band plays, etc etc.
You also get an interesting perspective of people when your sober. And most times I end up being the designated drive for all the piss heads on the way home and let me tell you having a packed car of drunks going from A to B, it pure entertainment right there in it's self.
