I love stuff like this. Another Roadside Attraction.
Here is some additional info:

The last time I drove through Florence was in 1988. I had a '68 912 and I was moving from San Diego to Patuxent River and had 30 days to get there. April time frame so I drove the entire length of Rte 1 to 101.
I had no idea I was driving by history!
