So we get to Hertz.  We unload the car, gather up all our gear, unscrew the Action Cam from the mount attached to the rear view mirror….and leave the mount hanging on the rear view mirror.  D’oh!  I called Hertz right away but despite our pending departure they weren’t able to grab the forgotten clamp and run it over to the hotel before we left for Canada.  So anyway, I filled out the lost and found form with Hertz and sent a tweet to @Hertz who jumped right in and said they were on the case.  A couple of weeks pass and I get an email from someone at Hertz asking to confirm the details and then an email arrived from Inga at Hertz in Iceland asking me how much I wanted to spend to ship it.  The next day I get another email with this attached.  And then a week or so later the clamp has arrived in the mailbox.
