Depends on how "safe" you want to be. Probably as likely getting killed in a car accident if you drive.

Wife and I are 66 and will be going through the Miami airport in a couple weeks and on to the Bahamas. But we will be on a liveaboard boat so only be exposed to about 20 people there. Not actually going on land in the Bahamas, as far as I know. We stay on the boat and the customs checks our documents, or at least that is how it worked in the past. We do have to get a covid 19 test no more than 7 days prior and be disease free before we go though.

Living is a risky business. Just depends on what degree of risk and reward makes it worth doing.

Personally a graduation I would find a good excuse not to go, but that is just me. Covid makes the perfect cover story for not having to attend weddings, funerals and graduations.

I'll wear a mask on the plane and in the airport because it is required, but here is kind of what I think pertains to masks.  Dr Gundry, short video.
