Your much more brave then I, however is far is the law is concerned you were good! I do think this is a social thing you and meny don't get becouse of AS, I mainly go by the laws myself so I can understand how it could happen, I will say though I get a little on edge when someone stops outside my home and mills about the fence looking at flowers, nevermind taking photos so I likely would not do exactly as you did. However if you are OK with doing this go or it, as I said its legal.
