Please Obscure Location Better

I am not comfortable with how rapidly this site could be discovered using simple web tools. Describing a rectangle bounded by the 215, 10, 60, and 15 freeways would be safer.

We already lost the "largest tree in Socal" (http://www.desertexplorer...) and the largest Joshua tree (Robinson, JW. San Bernardino Mountain Trails, 6th ed, Wilderness Press: Berkeley, 2006, p. 83) due to deliberate vandalism and stupid behavior.

I agree entirely it would be nice to obscure location. For exactly this concern we did not initially report the lat/lon of the tree, but reviewers requested we include that information. And you are right to be concerned: I am aware of at least one online video documenting an attempt to find this tree!
