@Brian P I don't agree with proof of vaccination for the following reason...if you're vaccinated and in relatively good health, then you shouldn't be too worried about severe complications from the virus...those that aren't vaccinated should be the ones worried about the possibility of severe illness...if people who are vaccinated were 100% proven to be virus free and/or unable to be contagious and pass the virus on, then keep the proof as a mandate...however, we know that being vaccinated does not prevent you from getting ill or from spreading the virus, so really, what's the sense...
as for testing prior to getting on a plane/bus/train whatever within 72 hours, I too think that's ridiculous...for example, my co-worker is going to Portugal for March break...he leaves Friday after school so planning on getting his PCR test on Wednesday...so say it comes back negative?...great, however, that doesn't mean he might not have caught something in the time between getting tested and leaving?
honestly, with the amount of people that have already had any of the variants to date, we really need to stop with all these mandates and start learning to live with it, just like the flu...
