Flattest low-traffic route NE to SE

[bikejunkie]

For any of you who have ever struggled with a trailer between SE Division and Burnside, or Portland to Woodstock, here is my favorite route. It's as flat as possible with the exception of the climb from Division to Powell (southbound).

Notes: if you're going north and want to avoid the hill north of Stark (i.e. bike move style), you can try this alternative
