OAK

Oak '03: Pick any couple or pairing. One member plans to celebrate a day of significance to them...could be first kiss, first glance, first year together...whatever. The celebration can't go off as planned in part because the rest of the team doesn't realize the couple you choose is in fact a couple and have committed the frustrated paramour to being elsewhere.

Oak '05: Let there be travel. On a boat, plane, car, train, bus, horse, wagon, bicycle, spaceship, camel, or dog sled - long road trip or short jaunt. Here's the trick, though: the story should take place DURING the traveling, rather than before or after. Overnights in the middle are okay, but preferably focus on the "in transit" parts.
