not perfect, but i’m giving myself a gold star for that (… the other one’s almost as nice!). the first section was relatively flat and on sandy jeep track for about 5k’s, after which one mother-of-a-climb started (and seemed to end just before the last 500m to the finish!). we can settle a wide range of windows, from old style windows to most recent sliding windows. some liked how the bag the top of the bag rolled easy when pulled by the handles.
