2014: “While driving in heavy rain at highway speed my wipers went all the way to the driver's side of the windshield, and stopped there.

I was approching exit236, so I exited and located a home depot parking lot just off the exit. I pulled into the home depot parking lot and upon checking the battery compartment door, found that the door was secured. What I saw was in fact, the battery compartment door skin. …”
