Mystery Pic

So here's my picture for today. Go ahead and guess what it is. No hints here, but I will put the answer in the comments.

It was raining as the Missus and I went to the grocery store. I turned off the ignition of my 4Runner and the wipers stopped in mid-stroke. This is a close-up of one of them from inside the cab.

@dutchothotmailcom Turn them on again? Great idea! Too bad I didn't think of that...it would have saved a lot of trouble! ;-)

Windshield wipers! Very cool - love the water drops!
