Mid week in a busy july

On my way to the mail box to retrieve the mail, i decided to spend just a few minutes and pull weeds in the small front flower bed. Not a big space at all. stella d'ore day lillies and a few black eyed Susans.  also a small frogy bird bath for effect.   just a hand full or 2 of weeds..... maybe 4.   Pulled, pulled and as i was walking away i noted major movement.  a SNAKE.   Probably a garden snake, but it doesn't matter, a snake, is a snake, is a snake.  about 15 inches long too.   His tongue was going a mile a minue.  He was quite agitated (so was I) and then he disappeared into a hole in the ground.  Here and gone.   i thought mice lived in that hole.... or maybe they once lived there?
