I decided not to "maahhh" at deer anymore because I got to thinking, what if your specific "maahhh" at that pitch or tone means, hey imma beat the living !@#$ out of you, in deer language? -or- your "maahhh" sounds like the equivalent of a superdeep-voiced 250lb brunette looking for a willing participant? Thus I've settled on a "pssst" becauseI think deer will investigate any sound that isn't threatening to them.

I wont stop slow walking orbrowsing deer though.
