I kept wandering around the botanical garden looking for things to catch my eye . It's a big place, 79 acres / 32 hectares, right in the midst of the city. The entrance to the boxwood garden caught my eye for its artful symmetry. Now, I know less about bricklaying than I do about how my computer works but how do they make such perfect circles out of rocks and mortar? Maybe we'll have a look inside tomorrow.
