I'm with Humuyan and the other posters here. Get some advice or watch how others do it and it will come to you as second nature once you have it nailed a couple of times. I would add the purchase of a good quality compass as you will want to know where 12 degrees East of South is to find the SCP, don't worry that you can't see it.
Of course if you have mind your mind up that this is not for you then Eric's advice is about spot on and I wish you well.
Good luck with your choice, I know which one I would be making and it includes a trip to Snake Valley
