The "HenBo" Big Lunch went very well. The rain kept away. About 200 people attended including the Mayor of Lewisham. Apart from lunch fun was had with a musical parade, a treasure hunt, fancy dress, a game of football on the lower slopes of Hengrave, a time line for the history of the area and a suggestion tree.
There are few photos on a new local community website.

Apparently there were 30 Big Lunches in Lewisham.
Maybe in your street next year?
