The Helena Brewers of the Pioneer League are being sold to Ron Romaneski of Yakima, Wash., but officials say the rookie league basbeball team will remain here next summer. Chuck Langerveld of Lake Havasu City, Ariz., who has been the team's sole owner since 1985, said Saturday he is in the process of selling the team to Romaneski, partly because the team's general manager, Ward Goodrich of Helena, decided to retire.
