We are going for our day 4 test tomorrow. It will be interesting to see how long it takes. Took well over 48 hours to get the day 0 test but we are having a great trip. Very few boats and lovely weather. Sailing from beautiful spot to another beautiful spot is not too oppressive. I just hope they get the tests back so we can go home at the end of the trip.. If not I guess we will just keep sailing around.
