 Three years later, the controversy had still not faded as Eastern U.S. Free Flight Conference president Robert Langelius told Congress that the USFWS had been "completely intransigent" and that many enthusiasts had given up the sport for lack of available space.FWS was also criticized by animal rights groups for its decision to allow bowhunting of deer on the refuge during the state season in the fall, the only hunting it decided was compatible with the refuge's mission.Most bowhunters, it responded, will be using tree stands on the perimeter and will only need to enter the site briefly to retrieve any kills.
