Don't know personally but based on the comments you got about private land, maybe you focus on migratory pathways headed down to those areas. Info is on the DOW interactive mapper about winter concentration areas and migration routes (very generalized). Sounds like your best bet is to catch one trying to move from public to private land. I am sure there are always many moving early and out of your reach unless you have permission, but that there's likely a bunch of deer bringing up the rear, especially if you get lucky with the weather.
I found this on another forum from a few yrs back if it helps.
"I know a little about 38....worked there for 2 years and killed a couple average bucks. A 172 and a 165 with the ol recurve. Saw a couple big ones. though. I don't think it is as good as it used to be but I would study your maps and any public land east of Highway 72 that runs from Nederland to Blackhawk would be a great place to start. Good luck finding private that will allow you on, they are a bunch of friggin tree huggin hippies that think deer should be pets. Oh, buddy of mine smoked a 215" in there too with his recurve....for what its worth Study the maps you will find some.............."
