And the answer is.....

Roscoe's Grocery on FM 2769 is now closed, and the letters have now
disappeared from the sign, but apparently proprietor Leonard Cunzalo had
some minnows and worms to rent out for fishermen who don't intend to catch
anything!
By the way, Roscoe is a dog, not the owner, and was probably responsible
for spell checking the signs!
Prior to opening the store, this sign had a message that said "OPENING
MIDDLE OF SOON" - too bad I failed to get a picture of that one.
Got an interesting picture to submit? Send it to: Lonnie
