I have successfully created a story map out of some points. The process was great - simple and easy and my non-GIS colleagues loved how it turned out. I have done a brief search for the same sort of template for a trails layer (lines), but haven't been able to come up with anything.
We have a web/app developer telling us it isn't possible to make a map similar to a story map without breaking up my feature class into separate shapefiles for each individual trail. This would be awful to maintain, so I'd love to prove them wrong.
