I took these evp's back in 2006 at Kingsley Plantation. Here's a link from Parks and Recreation to tell you more about the location and history
Visiting Kingsley Plantation - Timucuan Ecological & Historic Preserve (U.S. National Park Service) .
The pics in my album are from the same location and if you're in the Jacksonville Florida area I suggest a trip there. I've never walked away empty handed and have seen orbs there as well as gotten some pics and lots of evp. Some of the evp you can barely hear and I haven't tried to clean them up because I am afraid I'd lose what was there.
It seems to be most active during June-August.
I have more than this on my audacity files but I have to figure out how to save them all separately...yeah I've not been active in a few years...shame on me.
