Wish I could help Carol but as you know we returned to our home last Wednesday. I brought back with me some great memories.....and covid. Tested negative last Tuesday, flew home Wednesday and started having symptoms late Friday. I assumed it was a bad cold so didn't test until Sunday morning. Yep.....came up positive. Am glad I got home O.K. but have no idea how, where or when I came in contact with it. Good news is I think I'm over the worst of it.
