LOL something similar happened to me in Tennessee. I was in a college campus and walked on top of a piece of land rumored to be “sacred”. A group of guys confronted me and said “Yo dude, you can’t walk there. This land is sacred.. blah blah”. The funny thing is that land was open (with no fence) and there was no sign either. I told them I’m new here so I didn’t know and they understood. In situations like these, I would say it is better to try not to heat up the situation and walk away as soon as you can. Of course such ritualistic beliefs are dumb but there are people who strongly believe those and if they suddenly hear someone say it’s stupid (even though it is), they can think their personal beliefs are being attacked. Plus such events are not worth wasting our energy on.
