Doesn't sound silly at all to me - its like having a doorbell on the gate! Its also not obviously a security device, which is also good. They'd have to be out of the wind of course, wouldn't they, otherwise they'd be set off all the time. I confess, I don't like constant sound like thatWaterbaby wrote:Sounds silly,but I used windchimes in places where a gate/door/window opening would knock them as early warning to people entering or (children) leaving an area.
Cheap as chips,no installation as such,and effective as advance warning.
