The first part of this video is on the park 100 yards from where I live taken yesterday, the wooded area is a little further at 400 yards today, so when I say I am off for a walk you know where I am off to, there is no sound apart from a few birds chortling away in the wooded section
This sundail cut into the turf at Kesgrave, you have to stand on the month of the year you are in and it will tell you the time from the shadow cast from the sun [when it shines of course]
