A nice looking map, good job. It will probably be tough on low end pcs. My fans are staying on high just driving around the map.
I'm starting on the cattle farm in the lower left corner. I wish some of the trigger icons were visible, like at the bale storage, but I will get used to it or can use F5 to find them. You probably should let people know they will need a blower mod to use the harvestore silage silos.
