I remember flying before 9-11 and thinking about the minimum wage contracted employess who were responsible for airline security and how easy it would be to compromise that system-so in that sense I'm glad that the current TSA staffers have some training and that somebody ( I hope) is doing a good security check on them before they are on the line (though, as line workers everywhere, I'm sure they are at the bottom of the organization for pay and benefits) Anyway, all this makes me appreciate bus travel-cheap, boring,uncomfortable at best, no security at all from my experience- somebody once said if you don't think there is a class system in this country, drop by your local airport and then your local bus station-anyway nobody cares what happens to bus riders, so terrorists, TSA and everyone else pretty much let you be and if one of your fellow passengers decides to cut off your head and eat it on your trans-Canada ride, that's just life on the road...
