Giant Courgette

This year we've had an allotment for the first time, so decided to experiment and put in different vegetables and see what would grow the best.
It has been about 10 days since we last visited and things have gone a bit mad.
Here's Janet with a giant courgette or what we are now told has become a marrow.
Not sure what we're going to do with it yet, there's been various suggestions ranging from stuffing it to making it into chutney.
Decisions, decisions!
