Simple just avoid mA$$!
Let them destroy tourism in their state. People will see they have plenty of things the can visit/do locally, no need to travel.
Watch as next year they are begging people to visit what is left of their tourist industry.
I can easily avoid Mass. I have absolutely no reason, or the funds, to go there & now they have made it even easier. Suppose someone just wanted to go there & see a few sights & return home. But they want a lengthy quarantine? That would tend to make a decision for you I guess. An easy choice has already been made for me. I wouldn’t go there now if I was paid.
