We are also in Northern California and went to the same cancelled acro meet. Yes, I say went, because the cancellation email was sent to me after I had left town, and I was not able to access email from phone. So dd and I drove 3 hours in Friday pm traffic, checked into hotel, and were heading out to get dinner when we ran into another family from our gym who told us the news. (They had decided to make the trip anyway and visit friends.) There was no way I was getting back in the car at that point to drive home, so we stayed the night and visited a museum today before heading home. The frustrating thing was that less than 24 hours before the cancellation email, the host gym had sent an email assuring that the meet would go on but outlining the reasonable precautions. So I was not even thinking about it being cancelled when we headed out.
FWIW, the museum had many visitors, the two restaurants we visited were packed, and the Target we hit on the way home still had plenty of TP. In other words, we are not exactly hunkering down in hazmat tents around here. (But I am seeing lots of particularly vigorous hand washing!)
Ty's Dad, hope your daughter is ok!
