...yep, clear visual clues seem to be lacking in most of these images. Egbert and Shadowrunner had it easy. ;)
More brainstorming on this area.
I don't know how old that motel is, but it looks like it might have a fragment of green picket fence as well.
Turning on the spot...
From right to left, cannon, red hydrant, wall pillar.
The wall has a distinctive curving shape which is perhaps echoed in the rock and clouds of the image.
(Wondered about the base of one of the dividing pillars as another possible spot...might be worth counting them down from the main entrance perhaps. Considered the hydrant because of the fountain/rain theme. Looking down it might suggest the "monument" shape on the flag.)
By the cannon, the wall bends in and the verge opens out into this area:
Here's the other side of that signpost shown above, with a very dodgy 20 in the flag:
I'm wondering if the place where Ponce de Leon has planted his flag might be an indicator. There's also this pole opposite the motel...not sure exactly what it is, maybe a telegraph pole or lamp...
The cannon is still my favourite...it's just tricky to pinpoint a location there. Maybe there's a detail in the iron railings beside it shown above. The back of a cannon is also called a "cascabel".

(Since this is a Spanish name for a rattlesnake...also small bell / rattle / chilies...I was going to look for any of those hiding in the pic. I also suspect the horse is hiding something...I'm not aware it's been accounted for yet...? Cascabel seems to be a sleigh-bell. Perhaps the horse's cannon bone.)
BP did seem to like that salt cellar, with the repeated suggestion of "silver salt" towards the end of the verse. "Casque", which appears on its sign, and "cascabel", are both thought to be derived from "quassicare", to shake.

There's another etymological trail for cask/barrel, which gives us gun barrel...

Here's a statue of Ponce de Leon "created in New York in 1882 using bronze collected from English canons that were salvaged when the English attacked San Juan in 1792"

It's in San Juan where his tomb is, though there's a replica in Saint Augustine (beside the Bridge of Lions, which takes us back to Milwaukee).
