We just got Bananagrams too. What a great learning game! Love the fact that it's a travel game too. We have friends that keep this game in the care so they have it on hand if they have waits in restaurants, etc.
Can't beat playing board games by the fire in new england! For outdoor fun/educational activities my fav is winter nature walk. Bring along an animal tracker book to identify critter's footprints in the snow or mud -- depending on where you live.
