Well, I could try it down on the fence, but like I say when I get down there, I'm not sure the visibility above the trees is any better to the east and west because it's so much lower and the trees are all 80' high or more.
It's not just the height of the trees, it's the horizontal distance from the antenna location to the trees, too -- the elevation angle above the antenna location (elevation = arctan (tree height/distance to trees) (in this case, "tree height" means height of the trees above the horizontal plane of the antenna, so it includes any difference in the ground height at the tree location, as well).
At the end of the day, you want the most open sky you can get, particularly the southern hemisphere of sky, but the lowest elevations (say, under 20 degrees elevation) are not nearly as important as 20 through 90 degrees.
