I came across this sign at Vimy Ridge in France. It is a beautiful place to visit, but not without its perils.
You can walk into the craters if you wish; other than the sign there is really nothing to stop you, except a strand of rope. But you do so at your own peril.
Vimy was the site of an epic First World War battle, the most famous of the ones fought by Canadian troops. There were millions of rounds of artillery shells fired as part of the campaign. Not all of them exploded as they hit. Some are still there, buried in the French countryside, still powerful, just waiting for someone to step on them and set them off.
Yes, you can walk into the craters if you so desire. Might make a new one of your own if you do, but I believe in free will.
I didn’t take the risk, and lived to tell the tale.
