With our high posi test rate, let's say we're at the upper side of the CDC's estimate of real cases, 7-10x documented number. This would put our cases at 455k - 650k, which is .15-.22 of our population. If we do start hitting herd immunity walls soon, this summer surge could've been a relatively good thing since we got it out the way somewhat before flu season. Of course, we may just keep piling up cases too, but fingers crossed...
