The "Amber Waves" reference because of the lake, there could be an amber light that shines on the lake causing amber waves.
Also one of the hints was Droid Designate #12 rocks....as in the song Cleveland Rocks. maybe its at Drew Carey's house.lol
Ya that also points out Cleveland, there are also a couple others but I don't want put them on the forums.
I missed the rocks part. It will be in the Cleveland Area. Good Luck getting it. There is no way I will make an almost four hour trip to be late getting the phone by 3.5 hours. Maybe they will put the certificate by that big red stamp.
Edit: or maybe by the Christmas Story House.
