Tuttle is great for deer. I've seen some guys take some monster bucks north of Tuttle and Milford but they are also very busy places. Lots of hunters
If you can get a little further west of there into North Central KS. They have excellent bucks and a little less pressure depending on where you go.
Let me know if you have questions about any specific places in KS and I'd be happy to tell you what I know.
Good Luck!
