A storm drainage ditch across the street; it is blocked by homes on one side and open to a sidewalk/street on the other. There are also 2 drainage ponds, also partially surrounded by homes. One 2 blocks away, another 4. Only way to any of them is via the street.
Now the stealth part. There are few sections where I can get access to the storm drainage ditch, but still it would mean walking down a street. The pond would be easier. Visit a neighbor, walk across the street and sneak behind back yards.However that would mean climbing fences and risk being shot at.
