My experience has been if I am in the woods and I urinate, no big deal. The deer just walk on by (Actually, this year, now that we have a point restriction, they sauntered by, flaunting the fact their racks are too small).
If I am in a small stand of trees in a field, the deer seem to avoid getting to close to it if I have urinated anywhere near the small stand of trees.
The biggest problem I have is what to do with the cigarette butts?
