Livery Stable (Building; 1 in deck)
At the beginning of your turn (before you roll the dice), you may select one type of resource. For the remainder of the turn, you may move resources of this type between matching regions.

Example: If you have 2 forests, you could select lumber at the beginning of your turn. For the rest of your turn, you may move lumber from one forest to the other. You may make this move in both directions, and may do so as many times as you desire during that turn.

Since you must choose a resource before you roll the dice, you cannot
use the Livery Stable on the same turn you build it.
