Some landings are privately owned, some are on state property, and some are "managed" by the US fish and wildlife. The landings that are "managed" by the USFW will have that sign on them, which apparently carry a fine if used. From what i have researched, as long as you do not use the "fed's" landings, you will not get a ticket. The chief warden of WI is quoted as saying, "as far as we are concerned, it is business as usual. You just may not be allowed to use certain landings. If a federal warden attempts/gives you a ticket for hunting the upper mississippi wildlife refuge, that particular federal warden can/will be sued by the state of WI for hunter harrassment". Soooooo, as long as you don't use the "fed's" landings, all should be well.
