There are two nice campgrounds in that area... Pokagon State Park is probably 10 mins or so to the east in Angola and Chain o' Lakes State Park is about 30 mins to the south near Albion. There is another very nice FWA property called Tri-County FWA located about 10 mins straight west of COL. It's around 3,000 acres and is very scout-able for someone not familiar with the area as it's mostly open ag fields broken into sections with fencerows/small woodlots. I moved and haven't hunted it for about 10 years now but it was never very crowded during bow season, especially during the week.
I don't camp much but I know both campgrounds are highly regarded (especially Chain O lakes). I would just confirm they are open the weeks you are planning to hunt.
The best time in '23 will be the first two full weeks of Nov. Gun season doesn't open until 11/18 in '23, which is as late as it ever opens in IN, but you will want to be done bowhunting the public areas by that date I'm guessing. Good luck!
