Went on Sunday and Tuesday, concur on the lighter traffic. Very similar to 2015 when people thought that refugees are camping on the wiesn and that we needed a security fence.
It seems people are still concerned about covid, I had a few friends cancel a few days before. I'm fine with lighter crowds, hope everyone stays healthy. Cracked one my crowns on a brezn the first day and went to the dentist yesterday. He mentioned that I'm his first Ofest customer (it seems the nuts and beer mug incidents give him good business each year) and that friends of the family got covid already after going to the wiesn on opening day.
