Ok, if you don't miss, why don't you go set up your range in a shopping mall?
Sorry, to be so pointed in my communication. If that picture is the result of an accident, then it is what it is, accidents happen and it's just lucky that the fan stopped the arrow.
But if anyone intentionally aims at their neighbor's property, at all, and on top of that at an angle that will send arrows upwards of 100m when they miss... Then that person should not be having a bow in the first place. Sorry to say, but while bows may be sporting equipment, they can still be dangerous, and doing that kinda stupidly dangerous shit is bad for the whole community.
Supposed to vent warm air out of attic to cool down house. However these have been shown to be ineffective. The recommended method is radiant barriers and insulation, which works in winter as well as summer.
