car lags an

so Shutterwood vehicle?

Shutterwood Raft, that feels more like a blue card, but we do have canals here... ooh, maybe not a raft, but a bridge? Doesn't rly fit car except cars drive on bridges so thats my justiifcation

Okay so Shuttering Bridge... well that has a construction term, so maybe just Shutterwood Bridge. okay and it's going to be a fortification lol

this funnily enough has the same costs as darksteel garrison, the only other fortification
