The bin at our local park is a big bear with an open mouth to put litter in. I'm quite laid back but it's pretty gross with flies swarming round etc and of course ds just kept wanting to go over and stand up against it and peer in etc. tbh I'm sure he'd be the same if it was a boring metal bin but I'm not sure why they deliberately make something that most parents would want to keep DCs away from so appealing to them!
