Hither & Further Rumelia, east of Sofia

Having not heard from anyone, I'll continue with Bulgaria:

Sredna Gora is a small mountain range, just 40 miles wide, with four peaks rising above 4,800 feet, with locations all shown on the map above (they're not just symbols!).  The elevation on the left-hand hex assured it's lack of infrastructure ... remembering that it would be even more wild in the 17th century than it appears on GoogleEarth.

There's a gap in the infrastructure that runs south from here, dividing "hither" Rumelia on the west from "further" Rumelia on the east.  Then it's dense infrastructure again before getting out of Bulgaria and into Macedonia and Serbia ... which are just more wild mountains surrounding densely populated valleys.  It's a crazy place.
