Excellent concept. Weekend sailing with the family is a great choice for prevention of nature-deficit disorder. My kids like to combine it with horseback riding after school. It is totally afordable around here, but I guess prices are a lot higher in the US.

However, we must think twice before bashing video games, TV, etc.

Racing (differently from weekend sailing) may be an extremely stressfull and aggressive activity. The best racers I met are very aggressive, both in and out of the water.

I heard of a military study to determine the best sport for future officers to be exposed to. It seems that long distance ocean racing (sailing) was the sport that better simultated WAR conditions: prolongued tension under adverse conditions while depending on preparation, equipment, weather, team work, strategy, tactics, techniques, comunications and supplies to win against adversaries in similar conditions.
