I highly recommend it. I chose an old hospital in my city, called st marys infirmary ( in the location db for st. louis). I sat on the
first landing of the old buildings gnarly staircase. Looking up you can see
all the floors above you and all the missing stairs, etc. I was ready. I sat down and set it up, took my puff and held it in and waited. Within seconds the
most intense body rush comes over you as the visual rush if color, prism effects and patterns soon follows. The place looked alive, the stairs moving as if they were an escalator, the floor tiles around me spinning circles around me, and the walls warping and flowing in colors. The sounds of the wind through the hallways and windows made it seem as if the place was really alive and communicating. This all lasted
only about ten minutes, after which I just sat in awe at what I had seen. Do it.
I highly recommend it.
