There isn't usually line ups for the blinds. the trouble isn't getting them its getting TO them. The Hahn has been neglected pretty badly over the past few years and with the low water levels last year it was impossible to get in there. Maybe with the higher levels this year it will be easier but I doubt it. Pretty sure the only rules are no shooting from channel, two guys per blind, parking spot # = blind #, no motors, done hunting by 12 PM out of marsh by 2 PM and possibly no sundays? I think that's all there really is for regulations. Hope that helps
