When my daughter moved back to college in the fall, she had a 14 Hour drive to the East Coast. I was her co-driver, and I took the train back from Boston to Indianapolis.
In the first class lounge in Boston, I think there were three of us in the entire lounge. In Acela first class, I think there may have been three of us in that car.
The balance of the trip was in a roomette on the Crescent, and later on the Cardinal. All meals on board were in my room, I never ventured outside of my room further than the lounge car for a cup of coffee to go.
I felt about as safe as I could be out in public. I would have no qualms in traveling in a LD roomette or in First/Business on the Acela again.
I have also flown several times on business during the pandemic. I feel that Delta is as safe as you’re going to get on an airplane. I was not impressed with either United or American.
Ironically, I caught Covid on a driving trip. Many would say that driving is safer than either flying or the train. My opinion is that if you are out in public, you are at risk. I probably caught it while dining at a restaurant while social distancing, or possibly in the customer’s workplace (again, while social distancing).
When I venture out again soon - believe me, I will not take precautions lightly. I will do everything I can to stay away from others and putting them at risk. When I do venture out, it will likely be in a roomette on my way to a remote area where I can bicycle in a warmer climate for a few days while being completely isolated.
