I've met very few people who are completely disinterested in maps.
My map of Trammel's Trace attracts a lot of interest. When people stop at the visitor center at each state line, what do they have stacked at the counter? There are beautifully folded state maps that most everyone will take. On the continuum of map affinity from "how do I fold this back" to the truly addicted cartophile, there are more people on the love them end of the scale than not. That is especially true when it comes to old maps.
In this project I've been able to exercise fully my life long admiration of a well-illustrated map by researching maps of Texas, Arkansas and Tennessee over the last 200 years. The map below is one example.
