Well, that was exciting. I pressed "cancel" rather than "install", as I need to think about it. It is a Google+ app, that will take control of a whole load more of my life. I expect I will probably go ahead, (line of least resistance) but for the moment I'll continue to jump through the hoops.
Here are the pictures that I thought I would post;
Rosemary shrubs in flower above the Quarry Carpark in Guildford last Saturday
Tiny daffodils and irises by the front door
