For a minute, before following the link, I was thinking 'why not just look up the schedule? And, did you leave a RasPi on a bus?! Those things are like $200 now! Maybe you can get it back at the bus depot...'
Or you can try to monitor https://rpilocator.com more than the scalpers do, and you might be able to get one for $100 instead.
