Oh wow, that would definitely be a sight to see!! We have white deer in our region, called Seneca White Deer, and they are a rarity as well. Sadly a few years back someone or more than one were poaching them for their fur, and the population dwindled to the point that the stretch of road where they can generally be seen- protected behind the former army depot gate- was absent of them for a long while. Just the other day I saw my first one in quite some time, unfortunately it was not a convenient place to stop for a photo. But here is one I found online:
You definitely live in a unique place-- I've never even heard of white deer until now! That is very cool that you have seen one recently, nature knows what it's doing.
I wonder if the weather around the lake(s) causes the snow to linger longer, so that they developed this look for camo?
