Hi,
I think street lights are on later at night now to make the areas feel safer, yes we have "community Police" but I
think they go home at 6-00pm, but not to worry, we also have the plastic yellow signs saying "Police patrol this area"
, if they did you'd see them and wouldn't need the signs to tell you.
The tennis court lights I doubt would be on after 11-00pm, and if any animal was disturbed by them they'd only move out of the light a bit.
Max.
