We went to Otley antique vehicle extravaganza today. Not necessarily something of interest, just that it had fire engines for my boy to see and it's something to do for free. 
The smell of steam greeted us and then fire engines which also the paper deliverer from my work who had pointed me in the direction of this event. He used to be a fireman. My boy threw a fit being put in the fire engine as he'd just woke up. 
So he went on bouncy castles and slides to calm down. There were lots of vintage cars and bikes and a tank. Mostly the crowd was made of 'enthusiasts'.
