I once witnessed a helicopter land on Heys field.
Then taxis and cars arrived with people who were dressed in wedding attire.
The bride and groom got out of a limo and dashed across the slutchy grass.
The bride was struggling to keep her veil on in the downdraught from the rotor blades and was a dishevilled mess by the time she boarded.

I found the whole sight hilarious and wonder if on reflection the bride wished she hadn't thought this charade up.

I relay this event as a possible reason for a yellow helicopter.
