When tide and wind are just so, the boys (accompanied by a responsible adult*) love to go to the Hipple, a sandbar that is exposed at low water, it kicks up a bit of surf
It is guaranteed to wear the kids out.
*This excludes me, water is not my element, my excuse is that I grew up in Derbyshire, far from the sea where the water we see most of is rain**; mind you that’s not an excuse that you’d hear Dame Ellen MacArthur trot out. In an emergency I’d be about as much use as a chocolate tea pot, I’ll leave it to those better qualified.
**So I should be in my element today, it’s pouring down, British summers eh?
