We females urinate on the ground, not on the trees, but I've often seen deer watching me, waiting for me to move away so they can go after the salt. They don't seem to care that I'm on a low salt diet!

In sensitive alpine areas, it's often recommended that we "go" on bare ground or rocks so the deer, elk, mountain goats, etc., won't damage the vegetation.

Sometimes deer are just curious. I had one come up while I was napping and start pawing at my tent!
