Thanks, Steff.
Here are some pictures that I took at another multi-garden event, just up the road from where I live, a few year ago:

The guy in the first few pics is the comedian Roy Hudd, who was presenting the prizes that day. There was also a competition for the best scarecrows, which hopefully explains some of the rather odder pictures there ;-)
