can there be ONE safezone? like a boat or scrap town with vendors for supplies?

I could add a safezone, I think I'd then make it like a settlement in a cave. If I'd include NPC's it'd take long though, and I don't have the time to do so now, but I'll definitely consider adding a safezone in the future, thanks for your comment

Hmmm.A militia compund maybe? Like the military one but with militia / ranger loot

I could make a spawn for militia, but I don't know about implementing it in the form of another compound, cuz I feel the map is quite oversaturated with Military esc. stuff, so I'd probably make it more of a bandit hideout.

add gas stations along the roads (if not included already) to increase the map's likeliness to real life.

noted, might add one, but the map isn't based on a large section of a country, so 1 or 2 gas stations should do
