Picture 96It’s a 2300 year Asian tradition, but in Boston the Hong Kong Dragon Boat Festival takes on a life of its own. The nation’s longest running Dragon Boat Festival features killer races down the Charles River, but for those who are along for the ride, so to speak, there’s plenty to do onshore. In Cambridge there are arts and crafts demonstrations and tons of tasty Asian food. And anyone can come by and join in on the weekend of fun, because it’s free admission to this festival. For those looking for an extra special experience, buy a ticket with a group of friends for the 2010 Festival Banquet at the Heila Moon Restaurant and get into the spirit before the day of the big race.
