Good news - half the people there can't stand the deer eating their roses and would gladly see the population thinned out.
Bad news - the other half of the people there can't stand the thought of a single deer being harmed because they are like pets.
Access is a serious issue and if you manage to get access and the animal makes it to the next property after your shot then you run the risk of talking with the wrong 50% of the population to get your animal. I've looked at the little islands in that area a couple of times and talked to some people that would love to let me at it with a bow, but I haven't been able to justify the effort and risk. Just my 2 cents.
