Sad to be the bearer of possible bad news, but-
4 weeks or so ago, I arranged a trip to Boston & Philadelphia to look at miniature books at a bookstore in Boston and to hear (and tour) the mighty organ in Macy's, Philadelphia. 3 flights - Buffalo-Boston, Boston-Philly and Philly to Buffalo. 2 hotels, 2 car rentals and two CW concerts Worcester & Philly. Virtually all the tour with non-refundable prices, although from what I am hearing even if I had insurance, it wouldn't cover the cancellations!
How things have changed in 4 weeks! Anyway after talking to my Doc and local health department, both advise me not to go! Unfortunately, I am in the 15% bracket (over the 80%) and the odds go up significantly of severe problems or worse. Had I been under 50 say, I would probably have made the trip (taking all precautions). Had there been a test to see if you had already had COVID-19 (and developed antibodies - I had relatively mild symptoms after being in and around Wuhan last October 20th) I might have made the trip, but there isn't one yet. So the trip is cancelled.
I don't know if concerts will be cancelled but I suspect so. If States put limits on the number of people who can be together at one time (as I believe has just happened), that may force cancellations.
Anyway stay safe out there and wash wash wash.
