Just to throw a little bit of cold water, remember the pattern that emerged last year, cases dropped in May but began to sharply rise in June as the second wave hit and affected the Southern US as those residents retreated from the heat indoors to AC. This pattern is likely to occur again, it will be blunted by the vaccines, but the area of the country most likely to be afflicted in the coming months is the area with the lowest vaccination rates. Things could regionally spiral out of control there. I think the favorable weather pattern and high vaccination rates will make for an amazing summer in the Northeast and Pacific coast, the Midwest and Plains after a late start should be pretty good as well, but I fear for the SE (outside of FL, TX, and VA where vaccination rates are higher.)
