If I could get a list of everyone who's on your route I might be able to throw together a map from time to time that people could use to visually view how the routes are set up and what's on them.
I had a map I used previously that was accessible via an Imgur link. Now that we have note poles it'd be possible to just update the one map on my street when I get the chance, leave a note about when the last update had been made and link to the new image.
For me it was helpful to see the route member's name and a small graphic related to the route they were on. Now with the quantity of resource thing being an issue, there could be a small number associated with specific resources. For other things, such as player run businesses, there could be a brief description. It'd have to be brief though so pick the most important one!
