Pacific Post Office moved from this building into an old Bank of America a block or so northeast of this point (unnamed bank building on OSM house number 211)

Need to check alignment of Route K

Need to check if historical post office remains or demolished. https://en.wikipedia.org/wiki/Rembert,_Missouri

I'm not sure if Fellows Lake Recreation Area should be tagged as it is. Maybe a park rather than nature reserve? But then there's also "Miller Park at Fellows Lake", but I'm unsure of its boundary.

This note will track Fellows Lake stuff.

The lake is a reservoir owned by the city: https://www.cityutilities.net/wp-content/uploads/20200924-fellowslakeplan.pdf

They do mention conservation, land stewardship, invasive species management, so that could be a point in favor of nature reserve.

Partners with conservation department to offer hunting and fishing, but not an "official" state conservation area, though not sure if the difference matters: https://mdc.mo.gov/discover-nature/places/fellows-lake-springfield-city-utilities

I couldn't verify the name ends in "Recreation Area" either. I'll keep lookin. Any thoughts?
