No problem! Thanks for reaching out.

Bing's more recent (2020-07) streetside imagery, by comparison, doesn't go particularly far beyond US61, but the extent that I can see looks like it's all paved: https://www.bing.com/maps?cp=39.685407%7E-91.406978&lvl=17.0&v=2&sV=1&pi=-4.7&style=x&dir=273.9

Ooh, here's another image from around the same time, but that captures the surface of the road a bit better: https://kartaview.org/details/168144/4571/track-info

I'm having a tough time finding any recent street view imagery, but here's one from 2017-06 showing that it definitely was surface=asphalt at one point: https://www.mapillary.com/app/?lat=39.685325&lng=-91.410558333333&z=18.004759716642628&pKey=2912151322381165&focus=photo

Hi! Nope, I definitely surveyed it (as mentioned in the changeset: `source=survey`) -- I can't imagine that guessing would make for a particularly helpful map! That said, it was long enough ago that I don't remember the area particularly well, and would certainly believe that I could have made a mistake, especially if you have contradictory information. Unfortunately, I'm not sure how to view that ticket, so the claim that it should be gravel instead is pretty unfalsifiable to me at the moment.
