what about the weekender's dad and little Johnny and the none locals who are not registered and card holders
The way it works in Canada, is that dad and little Johnny are still welcome too. The basic idea of the scheme is not to discriminate against the general public but for the regulars to be known - and for them to report anything suspicious to the authorities. I have been to Toronto and just did my thing without any problems. The local Airport Watch guys were aware that I wasn't a regular but were satisfied that I was just another photographer. Had I done anything out of the ordinary I'm sure the cops would have been alerted and would have descended upon me in minutes. I also think that seeing a bunch of guys with AIRPORT WATCH jackets does provide some deterrent to would-be dodgy types.
