Gardening keeps you mobile

I met a local councillor who likes to make sure the public garden beds by the library always look nice. He was replacing plants that some idiot had pulled out.
I asked him if I could take his photograph- one to practice portraits and the other for Mono Monday the theme being mobile. Oh, gardening keeps you mobile he said.
So here is David busy and mobile.

Thanks to Skeena for hosting this challenge which I found quite difficult to illustrate.
