Only in BC! This is a true story my friend told me. He works in logging and on one trip out to work he was doing his log scaling and got a message from the mill. One of the logs that had gone there had damaged the saw blade. The log had a cannon ball lodged in it and since it was so old the tree had grown around it, so it was completely hidden. When the saw hit it, crack!
To put it in other words, it had to be over 200 years ago, ships sailed along the coast and for reasons unknown, fired at the shore. This canon ball was destined to tell its story.
