AYRSHOW

Not really sure about the spelling, the beach tractor was writing in the sand this morning.  It looked like he was going to add to the end of it but I had to go to work so didn’t see the finished work.
 
My dilemma is that the Ayr Show was a few weeks back and this weekend is the Air Show.  Is the spelling a mistake or a play on words?  I’ll have a look in the morning and see if anything is left of it.
