Even though it wasn't mentioned at all on the series, the "small Virginia town' where Hank was based out of was actually the real life town of Front Royal, Virginia. Kelsey himself visited the town just a few years ago according to local WZRV-FM/WFTR-AM looking for "things" to associate with this series.
Even so, I have my doubts anyone in Front Royal even cared about "Hank".
Interesting that when TV shows are based out of real life small towns..the names are changed but when they are based out of "big cities" those are more/less are kept intact.. I assume for legal reasons.
