Rainboots?!?

The days I drive to work I park under a bridge in the Sodo District in South Seattle. It is the only place to park unless you can get there early enough to park against the fence in the back where you arent under any of the bridge.

Well the days I drive my car gets bird bombed with bird crap so I have to wash my car every day so it won't damage the paint. I hate when my feet get cold and wet so I wear my rainboots while I wash my car. Recently I have been noticing that people driving by smile or look at me kinda wierd. Is it that odd?
