I have a single action that cannot be done until after an event occurs. I don't know when that event will occur. Yet, the action is essential and, after the event has occurred, will be urgent. I don't want it in my face every day while I wait for an event that may not occur for a month, but neither do I want it buried in my huge list of Someday/Maybe actions. What's the best way to handle this?
