We were lucky enough to make the right decision, and visit Westonbirt Arboretum despite it being a weekend and in the school holidays. Though the traffic was immense, once parked, the Sun came out and gave us the best of shows. As we drove out of the arboretum, the rains began.
There's a blipmeet here on Friday, if anyone's interested in meeting up. See the thread in the Community posts.
And now, although I have another few dozen shots to go through, I need to make the house a home, because my grand-daughter is having her first sleepover! It's slightly unnerving, being handed someone else's family jewel, but I'm sure I remember what to do. :-)
