Wow, it's taken me a while to post this...
Here's that photo with the see-through-woman. My explanation is that I have the camera on "night photo", which takes a while to take. The tour group was moving at the time... though, I've never really heard of digital cameras doing double exposures before. *shrug*
... and here are some other photos from the Bisbee Ghost Walk with the accompanying stories (still not all the photos I have... but eh... ). Bear in mind I took the tour in January and this isn't even half of what the tour-guide tells you on the tour, which is way more fun.
Below: Just a window advert' for the Bisbee ghost walk.
Below: This Fine Art shop didn't used to be a fine art shop... the building actually used to be two stories tall. The second story was lost in a fire. Reportedly, there was one casualty in the fire-- a little girl. She likes to play games with the owner and, often, customers. One of her favourite things to do in the evening, before the owner locks up, is to run back and forth across the second story.... which, again... doesn't presently exist.
Below: The Oliver House. There are some stories with more information than I have patience to type up here: http://www.sgha.net/az/bisbee/oliver2.html
Below: Two photos of the City Park.... where ghosts of children playing can be seen. One father had an experience with his daughter there... They were playing on some of the yard equipment and the daughter asked her dad if she could play with "the other kids" (kids he couldn't see). So she went over to the steps where she appeared to be playing with several kids. The father went over to play with his daughter, and she stopped and pouted. "Daddy, you scared them away and they ran through the wall".
Below: One last photo here... this is a shop. I really like this story-- not because it's scary, but because of the simplicity of the haunt. I can't remember much of the details of the place's history, but I do remember that there's a ghost of a little boy who peers out of that upper left window. From time-to-time, he can be seen waving at passers-by. I waved at the window anyway, even though I didn't see anything. Can't help but be friendly. =)
