what's the wire for? just curious...

I do not know. Maybe landscape lighting? The house was a foreclosure so
there are many enigmas, this wire just being one of them.

I loved the idea of digging the groove deeper, and then embedding the wire
half in the caulk and having the rest of the caulk above the wire.

Now it's off to Home Depot for the right caulk and gun.
