Teenage girls may be the hottest group of entrepreneurs around these days, judging from the first National Business Plan Competition for Teen Girls. More than 600 readers responded when we mentioned the program in this space last year. Among the winners: FUNdamentals, a summer soccer camp for girls, founded by two 18-year-olds from Yakima, Wash., Margaret Kowalsky and Rachel Rief, who had observed that young women tend to drop their athletic pursuits around the age of 11. The pair had actually started the camp a few years ago, which no doubt helped them put together their impressive business plan. For information about this year's competition, contact An Income of Her Own, the nonprofit founded by Joline Godfrey to foster economic self-sufficiency among girls. The telephone number is 800-350-2978.
