If your bubble has people in it who have access to psychedelics, then great. If one's people doesn't have that, "just talk to people" is profoundly unhelpful. That's a very odd and specific conversation to bring up within some circles.

Obviously certain exhibitions are more likely to have connections to this crowd. Favor those shows.
