Extra Keys

Thankfully I was home to day, because the neighbor husband was locked out of his house. He had come home after a long day at work laid down the keys inside, went out the back door to feed the pets when the wind came along and slammed the door. Lo and behold it caused the door to lock him out. I got a call to see if I had the spare key. It was returned after their trip. It was also in the locked house. So to make a long story short I am inspired to have a hide a key somewhere outside the house.  I have some pretty good hiding places in mind.  None of which are inside.....
