Whenever I'm stumped for ideas, my wife and I play a game. She has ten minutes to come up with a topic, and I have 48 hours to write a short story about it. It's fun for both of us, and it really helps with creativity and writers block.
This month, I was stumped for a picture for the August Wordsmiths challenge, so I asked my wife for a story idea. Without hesitation she said "a milk wagon." How she pulled that one out of the air, I don't know.
A Google image search for "milk wagon" turned up this gem. There's enough story fodder in there for a hundred tales. Have at it folks.
Stories are due by August 31 as a link posted in the comments section.
