Where do you find Suicune on Pokemon Heart Gold?

To get suicune you must have all 16 badges from kanto + the region you are from. You then go to a town I can't remember and it is it the upper right hand corner of you map. Keep going and foll ow a path. 5 or 6 trainers will be there to battle you and then you follow a path to a mini hill. a suicune will be waiting for you. You can use ultra balls to catch any Pokemon so if you want one you don't have to use a master ball because they only give you one for ho oh or lugia, which depends on which game you are playing GOOD LUCK!! :)
