The weather was a suitable metaphor for this evening's session; warm summer sunshine interspersed with heavy downpours. Up on Hinksey Hill, with wonderful views of the dreaming spires, we were exposed to all the weathers. Our task was digging / pulling up ragwort in collaboration with our friends at Oxford Preservation Trust.

It's a fantastic plant for wildlife, with yellow flowers beloved of bees, butterflies and moths, and it provides a home for over 200 species of invertebrates. Yay. It can also kill horses and other livestock. Boo. Seven of us dug and pulled, including Chris on his first GoodGym session. Together, we extracted enough deadly stems to fill a builders' bag.

The rain nearly missed us but we were treated to a lovely rainbow as we shouldered out tools and set off home.
