For me it's a toss up, New Orleans was pretty cool, My wife and I stayed in the Warehouse district. But my grand parents property in South of Traverse City also has some activity on it. It has some evidence of native cultures staying on the property in the long gone past. My archiology prof. in college knew my grand parents and had gone up to the property when they were getting ready to retire, because they were getting ready to build thier a house on it and retire there. My prof and I talked about the property and he said that there was evidence that a village might have been on or near the property. The lake that it sits near (50 yards) is a spring fed lake with the springs about 60 yards from the house.
I myself cannot decide. It's a toss-up between New Olreans, LA and Gettysburg, PA. I am going to both places again this year, so maybe afterwards I can truly say which is the most haunted.
