City appreciation

Why do we wait until we have friends or family in town to take advantage of the "touristy" things our city has to offer? I'm sure that many people that live in Chicago have never been on the architecture boat tour, walked through Millennium Park, seen a concert a Ravinia, gone to the Lincoln Park Zoo, gone to a sporting event... the list goes on. Why don't we take advantage of what the city has to offer regardless of who's in town? Chicago like many other cities has a variety of events and activities taking place throughout the year regardless of the weather, but its not until you have guests in town that you do new things. Why not do new things with the friends that live here? It would be like a new adventure in exploring your city, so that the next time you have friends or family in town you can recommend something that is truly unique to your city. Are we only willing to splurge in our city when we have a reason? Is living life not reason enough?
