What are you hunting for? For deer Onalaska is a good area, lots of animals you just need a lot of patience bow hunting and put yourself in an area that you see good sign and wait for them to come to you. I use a lot of scent eliminator stuff and find small clearings that have trails leading into them.
If your bow hunting don't expect to tag out on the first day. Its all about time in the woods doing things that increase you odds.
If your hunting for elk your guess is as good as mine. I personally believe they don't exist during hunting season.
