I've hunted states with Late closing times. The major
differences are the Toms can be very receptive
in the early afternoon 9 12-2pm range after those
hens have gone to their nests ( I have had great
luck in Maine hunting 11am-noon in the past
for the same reason ). Also, hunting near where you know
Tom likes to roost can be good during the last couple hours of the day ( I already can think of one Tom I had trouble with
last spring that may be in for a big surprise this year
as he makes his way towards his favorite roosting area).
Good luck this spring!
