Hey, I was a conductor on the Greem tram now and then - I instructed all passengers to show the 'guard' in the little shack their wristband as we passed. As they did I also verified everyone had one.
Can't speak to the value of any 'bag checks', since it is the norm to land aircraft and park them on the grounds, inside the fenced area, without bag searches or airplane searches.
I can assure anyone interested that I do NOT understand why they have chosen to nix the valued service. ALL the ridership sure seemed to appreciate it.
