Social - Acid around unsuspecting people ?

[MindNRA]

It always amazed me that you can do acid around people who don't know and in the end, they don't notice anything. So I am wondering what are you most interesting encounters where you were tripping and people did not notice at all.

Personally SWIY has two, he once talked to two hot chick police officers who were wondering what were we doing in the park so late and they noticed nothing. And he went to a big museum once and walked past guard, security people, hundreds of tourists, waiters at restaurant without anyone suspecting anything.

Next trial is a challenge a close friend of mine made to SWIY. He said he would notice if he was tripping and SWIY told him he would not. So in the next 6 months SWIY is gonna take a hit or two and head over to his house and see if he suspects anything.

What kind of stories you guys have?
