I had to come home a bit early as I was having smart meters installed. That was the theory anyway. The engineer took one look at my solid cellar and started talking about signals. Having whipped out his signal tester he declared the whole thing futile. It seems I have to wait for the next generation smart meters which will have stronger signals.
Still, I did find this smart Large White in the community garden, along with a Small White & a Comma. And later, bats and owls in the dusk down at Tong Park.
