Cool pics!
As far as Bigfoot goes, I have never seen or had experience with it but I also 100% believe that there are more than one species that humans have not identified. Money makes the Bigfoot story so distasteful, take away the flipping nut jobs and goofballs and look at some of the evidence. I believe something is out there but what that something is I have no clue!
As far as spirits go, until last weekend I had never had any run ins with them either. We did a ghost tour (my oldest daughter is all about ghosts) at Gettysburg. We did the Jenny Wade tour, long story short. Nobody can tell me that they don't exist, especially in a place where so many people died so violently and before their time. What I saw was not imagination, not alcohol or drug induced but it was as real as real can be.
Here are a few pictures that I can't explain, know that there was zero light except for the camera flash, my wife was taking the pictures with the camera facing the wooden joists. I keep saying its some type of reflection but if you notice most of them are the same size an shape.
Blow the picture up and look right below the floor joists
Look above the picture on the wall
This is after they turned the lights back on and my youngest couldn't get over to the other side fast enough to see the other "ghost" pictures. Look above her to the right side
