Green says masks will be last to go

[My 2 cents]

A friend of mine was refused entry to KTA because his N95 had an exhaust valve.

Because of this MM, I wondered about the mask you are using, but it seems you have it covered. But, if you are confronted by the mask police, don't you have to take your mask off to show them?

I too would like to say welcome back to Ironyak.
