A Lundy cousin told me the general area but said I couldn't get to it because it was on private land and posted. I had coordinates from the plot map and drove out anyway. Using my GPS I found it pretty quickly.
The old house is long gone but was on the river at the end of 104 Avenue East on the north side of the river. 104th Avenue dead ends on the river. Apparently the neighboring property owner convinced the County to close off the road. There is a gate across it about one half mile from the river.
There were plenty of No Trespassing signs on the fence along the road but none on the dirt road itself. Since it is still public property I decided it was not illegal to walk down the road. I jumped over the gate and walked to the river. At the end of the road I could not find any sign of the house. There were some old red bricks but from the photos I've seen the house was wood frame painted white. They may have come from the chimney or maybe just trash from someone over the last 100 years.
Ponce De Leon Mineral spring was also at this point but I knew it had gone dry in the 1920s
so I didn't expect to find any sign of it and didn't.
It was getting dark and since the adjoining land was posted I decided to stay on the old road and go home. But at least I found it and can say I was there.
