Liberty Caps aren't around yet (in my area at least) so you have time to try and find someone who has picked before.
Your best bet is to go picking with somebody who knows what they are doing, finding a reliable patch with no prior knowledge is gonna be hard.
If that isn't possible try and find out of at least a general area near you where they grow.
Study pictures of liberty caps online, or if you can get a book on mushrooms to take with you even better. Know what you are looking for before you go hunting.
Walk slowly around staring at the ground, it'll probably take a while before your eyes get used to it and start spotting them (it may help to actually lie down and look around at ground level to spot mushrooms poking up through the grass )
When you go picking for the first time you'll see lots of mushrooms that you are unsure of. Wait til you find one that you are positive is a liberty cap, and then use that to compare to others.
Once you find one patch look very hard nearby because there'll usually be more not too far away
Untill you know what you are doing only take the shrooms you are 100% sure of,
would it fuck me up if i smoke weed whilst tripping too?
Nope, i find weed enhances all my drug experiences. skinning up while tripping is grest fun too
