Funny story Roger!
I hope the mailman doesn’t get your chain stuffed into your mailbox like our toddler son did in his pint-sized front pocket of his Wrangler jeans one time. He’d found a short length of 3/8” chain and got it all stuffed into his pocket. His Mom was collecting the laundry and pitched his jeans into the collection basket. It when ker-klunk and knocked the basket over. She had to fiddle with it for a long time to figure out which link had to come out first to release the rest of the chain.
