i was thinking that it'd be pretty easy to set up a leaflet widget
to<br>
display an OSM basemap with OHM railroad data as a vector overlay,<br>
but then it occurred to me that Russ is frequently mapping in areas<br>
with no cell signal so that won't work.<br>
<br>
but OsmAnd (which i think is what Russ uses for his offline maps)
can<br>
import layers sourced elsewhere, so there may be a path there.<br>
