Riding the bullet train from Kyoto to Osaka, accidentally left my iPhone in the seatback pocket. Didn't realize it until way later, but was able to use find my phone to see that it was still powered on and had made its way all the way to the end of the line. Went to the local train station's lost and found, they called the other station where the phone had been turned in. They shipped it to where we were staying. I can't imagine ever getting my iphone back like that in the US.
