don't play with guns. Try not to wander off by yourself. Definitely start a bonfire in a safe location as long as the wind isn't blowing to hard, and keep at least a 5 gal. bucket of water on hand in case it gets out of control, and when you leave the fire, pour the water on the coals. Music is alway good. A lot of times people say "oh do this or that" or " oh, this is the best thing to listen to while you're trippin" and honestly, 90% of the time they're wrong. Don't be forceful in what you do. Keep the plans simple, and don't try to map out your trip because it won't work out. I'd tell your friend to clean the house if it's not already pretty clean. I hate being in dirty living quarters when I'm tripping, but that's just me. These are just some simple things to prepare yourself. Clean house. no guns. No walking off in the woods by yourself, as tempting as it seems (unless you know the area THAT WELL). Bonfire is key (my opinion)
