not important, but my search terms selected include various tricks to limit it to local relevance, "chalfont road" together with "wallace", maybe "marsh creek".  Of course, being a likely TIGER typo, it will make it into results based on the census data, whereas with general hand-typed results, I'd guess those are closer based on local dispersed knowledge.  Particularly when referencing the parking at the end.
Naturally none of this substitutes for a survey, nor eliminates the need for one, but is more an armchair exercise in futility, given the ratio of discovered inconsistencies to available and willing mappers.
(The italic font used for, say, park names, makes the o-a difference all but invisible at times, but not an issue here)
