I.... have no idea. It seems that boxes lower the WQD as long as you're not above them. There's 1 or 2 spots that reach 6000 max. And that's on each side of the saloon doors. The other 5000's are at each RSVF and CLA base.
Edit: Aw... 8,000 at CLA base and 6,000 at RSVF
*facepalm* Now I can see why maps aren't made like the real world.
