To help with aiming, use the maps option of TVFool
here. Zoom in close once you have your receive location (the red icon) set properly (it's draggable). Turn on the option to show lines, and the directions to each station will be displayed. You should be able to find landmarks that get you where you need to point. Once you've got the antenna up, tilt it up a couple of degrees to aim the peak gain closer to the top of the rise.
