  We gathered high resolution spectra for an ensemble of 55 bright active and
inactive stars using the ARC 3.5 m Telescope Echelle Spectrograph at Apache
Point Observatory ($R\approx$31,500). We measured spectroscopic effective
temperatures, surface gravities and metallicities for most stars in the sample
with SME and MOOG. Our stellar property results are consistent with the
photometric effective temperatures from the Gaia DR2 pipeline. We also measured
their chromospheric $S$ and $\log R^\prime_\mathrm{HK}$ indices to classify the
stars as active or inactive and study the connection between chromospheric
activity and starspots. We then attempted to infer the starspot covering
fractions on the active stars by modeling their spectra as a linear combination
of hot and cool inactive stellar spectral templates. We find that it is
critical to use precise colors of the stars to place stringent priors on the
plausible spot covering fractions. The inferred spot covering fractions
generally increase with the chromospheric activity indicator $\log
R^\prime_\mathrm{HK}$, though we are largely insensitive to spot coverages
smaller than $f_S \lesssim 20$%. We find a dearth of stars with small $\log
R^\prime_\mathrm{HK}$ and significant spot coverages.
