My gigantic climbing rose bush

i have a climbing rose bush (called "Cecil Brunner) that i planted about 8-10 years ago. it was planted outside my front door and has grown into this awesome, collosal natural arbor over my front porch. but it is so big, it has grown up onto the 2nd story (roof) and i can smell the roses as sitting in my room. jeff and i even trimmed it a bit this year and you really had to duck to get under it!
