***sarcasm on *** I say, make the zones and zone boundaries as complicated as possible to discourage newbies from taking up the sport. Make sure the different zones have different regs and different permit requirements, too, like the Horicon zone used to have. While we are at it raise license and duck stamp pricing and reduce hunter safety course access, and make the remainder of the waterfowl and small game regs more complex too. ***sarcasm off*** But seriously: I hunt on Lake Michigan (Door County) and probably at least half the years the ramps are frozen up before the end of the current S zone season, that is, by December 5, sometimes a lot earlier than that. So a later duck season -- to December 15 -- on Lake Michigan will not do me much good in those years. Whereas I do tend to shoot a fair number of ducks on Lake Michigan in early October (not divers).
