the worst spawning areas are the beach(mostly along the hills, and my mountain), I could add either some torchs or jack-o-lanterns to my mountain(neither would be out of character for my character, as he's somewhat paranoid about creepers and has a very large pumpkin farm).
I had also pondered placing more glowstone lampposts along some of the worse lit roads, but wanted to ask Deme first before i added anything to the roads or to the hill by the base of her tower.
