close call at pdx

This was a close one at the departure end of PDX. I was flying along and decided to get cleared though PDX class C, then class D airspace. I heard the departure of the Delta 737, but man it sure came up fast. I saw this big blur of white pass infront of my windscreen.... If FS9 modeled wake turbulance, it would have ripped my Cub to spinters.
