Dust

[jp10]

The main problem with the game's dust, IMO, is that it last to long. About 50% of a dirt/sand dust trail is heavy and needs a strong wind to stay aloft. The dust trail should only be thick for 4-6 hexes behind the vehicle. A vehicle that moves enough to raise a 12 hex dust trail should only have maybe 2 hexes of heavy dust and 4 hexes of light dust behind it at end of movement.
Probably beyond game code however.
