Oktoberfest in McLean

Organizers of this year's Oktoberfest in McLean say only Munich would have a more authentic celebration than the one they've planned Saturday. Ethnic food and drink, music, dancing and entertainment will be featured from noon to 5 p.m. at the McLean Community Center. Among the entertainment will be the "Die Alte Kameraden" German folk band, which has played at the Kennedy Center and Wolf Trap's International Children's Festival. Activities for all ages include a 10-kilometer Volksmarch (walk) through McLean, handmade souvenir steins, original Swiss, Austrian and German crafts and products on display, wine and cheese tasting, clowns, face-painting and a kid's Maypole dance. Contests for yodeling and the best-dressed man and woman are also scheduled. Admission is $2; children 15 and under are free. For more information, call Sam Roberts at 790-0123.
