Why do the gates exist in the first place?
It's not like they mean anything, given that the roads are owned and maintained by the county and are therefore public roads and anyone can access them.
While there may be some that get a feeling of (false) security, it seems to me that a lot of expense maintaining them and supplying gate guards and banks of monitors (such as in the gate building going into Tall Trees I think it is)...could be saved.
And yes, I'm ready for the onslaught of emotionally driven dissenting views.
