The pictures were taken at St. Mary's in New Salem, MI, Visitation in North Dorr, MI, St. Sebastian's in Bryon Center, MI and at an abdondoned, one room schoolhouse, also in Bryon Center, MI. This is the school where my Dad and my uncles attended first through eighth grade many, many years ago.
You may want to click on the pictures to enlarge them so you can see all of the orb-y goodness. There are no orbs that I can find in the last picture, I just thought it looked kinda cool...and also really creepy!
