So...it's my parents' 50th wedding anniversary this month and my sister and I have no idea what to get for them. We are taking them to Benihana with the immediate family this Saturday for the "official" celebration dinner, but we're lacking for other gift ideas. My father has had some health issues recently, so vacation trips that involve airlines are out of the question. They didn't want a big party with their friends, so that's out as well. Any cool suggestions would be welcome.
