Surprise in the palmettos

I was checking on the Ceasar weed patch I' ve been clearing and encountered a series of barely buried trash piles. Then I found more under a patch of palmettos nearby.
By the time I was done, I had uncovered enough to fill two trash bags.
This was a bit of surprise because I thought I had already checked this area for trash, but the palmettos have turned out to be a frequent dump site. I recall finding some transmissions in this general area in the palmettos.
