Portland - Course Familiarity

I have been looking at the Portland Marathon Course on Google Earth (via the link on the course page on the Portland marathon site). I'm 99 percent sure that I have run some of the course between miles 8 and 11 and the section of the course between 14.5 and 17 during my leg of the Hood to Coast relay in 2005. Familiarity is only going to help, because that is probably the 'worst' section of the entire race in terms of scenery and course support. I'm going to be in a great frame of mind during those sections for sure.
