Over near Huron, we regularly hunt along the roads and get a fair number of birds on day 2 or 3 of the season when the big groups (ours included) have pushed the birds in there. The one state land parcel we've hunted across from our private patch, I haven't seen a bird in there in the past 3 yrs but I'm told there have been some birds in there. Best situation would be to get access to some private land after the first 3 days from the openner. Access could be free or pretty cheap for the asking after the openning weekend.
The NID being reliable as a bowling ball, just the same, I'd bring a backup just in case.
