Seeing color

It rained here all day and of course, I had to go to the grocery store.  When I got out of the car, I happened to glance down (or my photographer's eyes just knew to look or something) and there was a big area that was alive with color.  The water was just barely covering the pavement here but apparently the oils and such from the cars was causing this rainbow effect. 

I know those people in the parking lot where just looking at me as a weirdo taking photos of the ground.   Made me smile!
