My original motivation was to have a category for the Knox Trail (a set of markers in New York and Massachusetts that note the route taken by Gen'l Knox to deliver cannon from Fort Ticonderoga to Boston in the Revolutionary War).
I looked at "things -> historic markers" and see that there are a number of per-state sub categories which is all good and well. However, what I was looking for was a category that was for both intra as well as inter-state historic routes. Also, the routes in question may not have markers, so it doesn't seem to me that that this category would be correct.
Looking closer, I see that there are others proposing similar categories: Santa Fe trail and Oregon Trail to name a couple. I could easily see someone wanting to have a Route 66 category, or keeping with the New York theme; the Erie Canal route. On the flip side, there is a Lincoln Highway category under Things -> Signs; but again, I wouldn't expect a historic route to necessarilly have markers/signs; the original bed of the Erie Canal doesn't.
Based on this, I propose a Things -> Historic Routes category, where subcategories such as the Santa Fe and Oregon trail's as well as the aforementioned Knox Trail could be hosted. Who knows; maybe even Route 66 one day. Individual waymarks could then be added to the sub-categories and allow people to visit specific waymarks or navigate an entire route, should they chose to do so.
Comments? Thanks for listening!
