I'm lucky, as I live on a farm my dark site is two steps off the verandah.
I'm quite spoilt to have a powered site with amenities.
I also have two killer attack cats, that is if they can ever wake up and drag themselves away from the fire and further than the crunchie bowl.
Like Paul, I've still yet to see the aliens but they are welcome for a cuppa.
The only weird noises are the possums growling and the roo's coughing up something I probably don't want to see anyway.
