I love walking through the streets with a camera. It's a great excuse to get some exercise and stay intimately familiar with your camera and lens. Sometimes you see things you wouldn't see if you stayed home and watched TV. If you've grown accustomed to the sights in your own city that gives you a great excuse to travel to the closest big or small city near you and start a walking exploration all over again.
To recap: Walking keeps you from getting fat and out of shape. Seeing new things keeps your mind interested. Sharing images gives you an intention that drives you to walk and see new things. I guess that makes exploring with a camera medicinal. That's my prescription for today.
