It might seem fortunate that the organ was being picked up from Gainesville, and so the transplant recipient may well still have received it at some point...
I had a look and think the NTSB prelim has the location wrong, as 12Statute North East of Palatka Municipal is the St. John's River.
I'm guessing the site is north west, which tallies up with the other notes about being south and slightly east of direct track - something I'd perhaps put down to the pilot knowing the area and looking for lower terrain (the elevations are 20m (63') higher on the direct track than a point at Georges Lake (elevation 35m (118') amsl). Assuming I had more background about pilot and the conditions he was directly experiencing.
There is one small town 4sm to the southwest, and little else, with higher ground to the northwest, and the small lake, which would have been passed just ahead and to the pilot's right hand side.
