We love to go kayaking or out on the SUP and have our regular places we go to but recently they have been places with people swimming.
We've been at one of our favourite places for kayaking this morning and two/three families were there when we got back but with no regard for safety as the parents were on the bank in picnic chairs reading or chatting and about 10 children were in the water. That spot is full of reeds under the water and the children called out to each other about it getting deep and it being full of weeds but the parents were taking no notice. We do go wild swimming ourselves but not in this spot because it does suddenly get deep (chest height for an adult in unexpected places) and there are a lot of weeds. It's got a sign on the noticeboard about not being safe to swim because of weeds.
