Further Rumelia, west of Suida

Here's the next map going west.

A portion of the upper Maritsa, the big river not named on the map, flows through the rough country between Suida and Kazanluk.  Today the valley is densely populated, but there's also a large reservoir that makes me think much of it's been irrigated by the collected water.  Either way, in my game world, it's a dense forest that separates the east population density from the west.  The infrastructure numbers at the bottom of the screen (742, 692, 484) shows that it's going to be all dense cities on the south side of this forested reach.
