If you ask Youngest Granddaughter this question her answer is he digs in muddy holes in the ground!
On Friday we went down to Clare on the Essex/Suffolk border to see the "muddy holes in the ground" which son is in charge off. It's a community thing, lasting for 3 weeks and this is the 3rd and final year of funding.
All that is left of Clare Castle on the top of the Motte
A view over the roof tops of the small old town of Clare from the top of the Motte.
I visited this church (one of the 100) when we went down to see the dig two years ago.
