Hazel stand .

One of a number of hazel trees ( I think ) which stand in a circle .
The circle is often occupied by small children having a Forest school experience. I tried to capture the circle but the results were disappointing so I’ve used this shot instead . Next time I will try a panorama shot .
I was up for a few hours in the night with restless legs and a restless brain . Today I made a big effort to get more steps in and managed 10,000.
One of the thoughts that kept me awake was this crossword clue in the New Scientist, what is the seventh prime number ?
I worked it out but it had the wrong number of letters , any thoughts ?
