The early antlerless seems odd to me. I don’t get the reason.
That specific firearms antlerless hunt is not open statewide. Its only open to certain zones which the DNR deems to have an abundance of deer available. So to me it says that the population perhaps needs to be trimmed a little in those areas.
Make sure you check the regs to see which of the zones are open for it. Also remember that anyone who intends to hunt Thurs-Sun will need additional blaze orange (like if you are a grouse hunter and only usually wear an orange hat or an archery hunter that usually just wears camo).
