Take along some breakfast (or find some delicious food at the festival) and enjoy this fresh spring day on the shores of Town Lake, at Festival Beach. From 10 this morning until 3 this afternoon, watch the races and take in the associated activities. This event has plenty to offer for children as well, who usually seem to enjoy the demonstrations of martial arts especially, and it makes a fine excuse to be ambling out and around. The promotional Web site doesn’t include all the activities, but most years there’s also an array of dance programs. The races are a real exercise in teamwork, usually requiring twenty paddlers, a steersperson, and a drummer to beat to set the strokes.
