All great advice. I'd have to say especialy the rubber boots and changing locations. If they keep going by you, is it always in the same place/path? If so, get down wind of it and put up a quick ground blind. Also, get a bug zapper and look at your clothes under the light. If they glow, the deer can most likely seen them. So instead of you being hidden - you're glowing! Good news is there's a spray you can but to cover those types of dyes. Not sure what it's called because my clothes don't glow, but if you do a search on google you'd find it.
Good luck!
