I have traveled for work all through the pandemic (for reference).
Been all over Ohio, Michigan, Indiana, Pennsylvania, upstate New York, etc.
I have had a piece of paper in my wallet since late February or early March that said I was an essential employee and was traveling for essential work for even when I was traveling during shut downs.
Never, and I mean never, has anyone asked to see it...
Until today...
I flew to Maine, got to my hotel, the desk has to ask everyone from out of state other than Massachusetts and New Hampshire, if they are traveling for essential business.
When I said yes, she asked to see my paperwork and had to scan it into their system for their state CDC guidelines.
My paper had sat in my wallet and never been used for 9 months, it was so worn/almost torn from just sitting in a wallet for so long that I apologized and told her I could email her a pdf of it once I got to my room.
Just weird and somewhat alarming.
Don’t think people won’t want proof of a vaccine for certain things in the future.
