ok guys,sound funny i know,so here is the whole story,i put the rock in black garbage bag then in my backpack,and it was heavy,my family(it was 8 of us)told me that i was nuts and that on the customs i will have nothing but problems.Well on the dominican airport everthing went well,they didnt even ask nothing,backpack was wet but not too wet,on the plane i put backpack in the overhead storage(stupid move)and after an hour(flight is only 3-1/2 hours long) peaple in the back start to complain that somthing is dripping,so stewardess ask what it was and i told her and she gave me a plastic bag and i put my backpack in it.Another stewardess came up to me and told me that i will have problems on the customs and it is better to throw it away,otherwise i will pay the fine,or if i want take a chance.So i went with a take a chance deal.On the Pittsburgh airport bag went on that screen machine but before i told them what i have,and they say ok,they did not even open the backpak,but another lady opened and she stick some kind of a peace of paper i guess to check if the water ok or something.At that point i tought it will be taken away from me,but all she did was gave me a brochure about what i should not bring in the USA,and she said because i didnt know i can go.So i was happy not because i kept the rock but because my wife was mad and she said i hope you end up in jail,so guys you can bring the rocks but not corals,just act like you didnt know :happyfish :happyfish
