If you haven't been to Feast on Film at Moors Bar (third Wed on each month) then I can strongly recommend you should give it a try.
At the last one there was a 'mockumentary" featuring a man who was into 'righting'. Wherever he saw a a shop sign with a missing letter he'd repair it guerrilla style.
Got me thinking, how long has BLOCK BUSTER sign been LOC BUSTER?
Anyone fancy taking up the challenge. (The secret is not to use the same font but the very opposite.)
