I used to do that all the time. I never had access to a vehicle, so it was just a place within a couple miles' walking distance. There was a park I'd go to, an old abandoned building, go to the mall & people watch, or sometimes just go to the store to buy a drink & go back. Now that I'm living in my new place, I don't so much need to escape outside (& it would be kind of dangerous to), but I really do enjoy just getting up & leaving with no prior warning or destination. : ]
