Methods  

canTravelerPass (traveler)travel.t[1664]

Determine if this barrier blocks the given traveler. By default, we don't block anyone. This doesn't make us much of a barrier, so subclasses should override this with a more specific condition.

explainTravelBarrier (traveler)travel.t[1672]
Explain why travel isn't allowed. This should generate an appropriate failure report explaining the problem. This is invoked when travel is attempted and canTravelerPass returns nil. Subclasses must override this.
