More than anything the psilocybin experience and message is one of migration through organic networks.
You need to be outside in a beautiful setting that you can explore. A local park that has established trails is really the best option. Preferably something with variation so everything doesn't appear too homogenous, like you dip into the woods and come out the other side eventually.
Select a reasonable and agreed upon loop or point of reversal so that you don't end up having walked for 18 miles through the woods in the opposite direction of your vehicle. Once a few buddies and I had to hitch hike back through a state park when we found ourselves in a similar situation and although it certainly proved interesting, the last 6 hours of the journey up to the point of salvation were very psychologically trying for all of us. Thankfully we all pulled through and nobody cried till the fat lady sang, then it was all tears of resolved joy. Getting lost in the woods can be a great thing, up to a certain point. At which it becomes a very bad thing.
DO NOT sit inside in a dark space, turn on a television, or fuck around with any electronic devices. They are totally antithetical to the whole thing, what with being electronic regurgitators of synthetic messages and all.
