Probably not a lot of ‘treasure’, just cannons, and the like..................
Hey, I’d love to have one of those cannons in front of the house.
Treasure comes in many forms. I live in the Gold Country here in California. While spending time gold panning on the Bear River, I realized that there is more value in the river rocks than the gold. Now we go and load up river rocks for landscaping. Its actually less work than looking for gold. ;o)
