Back to Buenos Aires today. As we were waiting to leave the boat, we saw the couple we knew who were friends with one of the individuals who tested positive. The told us that he had to stay in an apartment in Ushuaia until he was done with his quarantine period. His wife was moved to a hotel as she is still in quarantine even though she did not test positive. The flight back to BA was very bumpy. Happy when we finally landed. After grabbing our luggage and heading back to the Sofitel, we stood in line to get our final covid test to get back into the USA before heading to our rooms. In the evening, the group walked to a restaurant for our final dinner. When we were there, we were told that everyone in attendance had passed their covid test. We had a nice steak dinner for our last evening together.
