This cache is near some piles of gravel used by the railroad. Most people probably pass by without even noticing those piles, but to me they hold personal significance. Back before I moved to New Orleans I happened to be in town and through sheer coincidence ended up hanging out with 2 of my personal heroes. We biked around the city and ended up spending a good chunk of the night sitting on those piles of rocks, drinking adult beverages, watching the train roll back and forth, the lights of the bridge twinkling in the distance. It was a magical night and I think had a small impact on my decision to eventually move here.
Also of note in the vicinity, to the right of the pile of rocks is one of the few walls in the city, that I know of at least, that the owner has given permission for graffiti artists to do murals on (though at the moment it's mostly blocked by a bunch of construction stuff).
Also, check out the crazy tree house jungle gym contraptions in the back yard of the red house half a block down.
