I also keep most of my stuff by the back door. Messenger bag, handle bar bag, helmet, gloves, and shoes. Also depending on the weather, an assorted variety of hats and shoe covers. It's a little more organized than it sounds or the wife would kill me. We have a 9 cube shelf thingy we picked up at Target and I keep most of my stuff in that.
The bike is usually outside if the weather is nice or in the shed if it is raining or snowing.
