I checked in to the place  station today  and there no mask required if you have been vaccinated

still wearing mine in crowded public spaces, unless outside with some room, even though I am fully vaccinated.
 Too many people still are not vaccinated and there is no way to know who is and who isnt and pretty sure most without mask are not vaccinated.

I have been traveling pretty much the whole month and haven't been home.
Was just in a hotel last night and saw the mask optional sign if you have been vaccinated.
I have my vaccine and am so glad to not have to wear this mask in this extreme summer weather that Vegas is known for.

No way to know if somebody else is vaccinated so will still wear my mask for the time being around crowds

I'm only 1/2 vaccinated but even when i become fully vaccinated soon, im still wearing a mask afterwards, Im not gonna ask total strangers to show their vax cards plus like others said on the topic, some will still lie about being vaxed to not wear a mask. Since i take the bus to work, i have to wear it on there regardless.

LOL!   Do you blame them ?

I'm still wearing my mask in public, being vaccinated does not mean you are completely immune, it just lowers the chance of significant complications that makes you require hospitalization, especially with the emergence of mutated strains.
