Some people reading this will be itching saying "When are you going to get to the part about finding the blood dripping from the walls?" or "When are you going to tell us how to get more orbs in our photos?"
Get a GRIP people! Investigations are usually hours and hours of tedium resulting in very little to no evidence being gathered. Also, let's face it... it is FAR more common to hear about a ghost not being seen but heard walking about than anything else. Unless you're on some interesting pharmaceuticals AND hanging around Amityville, blood doesn't often drip down walls by itself... Sorry, most ghosts are NOT that interesting. And the reality of it is that most actual unexplainable or paranormal events are rare.
You probably won't get rich, or become an instant TV star, nor have an AMAZING experience, but it can and should be an interesting ride. Enjoy yourself and have fun and be observant. Experience-wise, it will all pay off SOMEWHERE down the line.
We believe it's better to simply get EVERYONE involved and realize that no matter what the outcome, how many people get to do these things for a hobby? It can be a great learning experience and fun to boot!
