Zaragoza to El Burgo de Ebro (actual)

Interesting landscape around the river. Some very rough stretches that are tough on our gravel bikes. Some kind of suspension would be good for this route. Note that the trip back is about 3 miles shorter as we did a lot of loops through the countryside. Note that there is a point about 7 or 8 miles along that loolis a little bit like three sides of a rectangle with the long side against the river and s small backtrack section on the northwest corner (I couldn't figure out a way to mark it in BikeMap). This is a place where we found a single-track hiking trail that was visible in sattlite photos but didn't show up in BikeMap. It took a bit of searching -- and  had to just head across a meadow with no obvious trail but a park sign that was visible about 25 meters away.  Anyway, it was a nice track to follow -- not technical, just narrow and poorly defined.
