Not quite sure how well outdoor table tennis will work, or where all these spare exclamation marks are being shipped in form, but this is fairly cool:
"Ping! England will be hitting Birmingham with bats and balls between 8th July and 8th August!
Fancy challenging a handson stranger to a game of ping pong?
beating your boss at a game?
You have 4 weeks and 55 ping pong tables to make this happen!
Ping pong tables will pop up all over the city, from Moor Street Station to The Arcadian, and from Chamberlain Square to under the Spagetti Junction.
‘STOP and PLAY!’ The notice will say
Free for all! (just borrow a bat and ball!)" [link]
