Hunter Management Areas (HMAs) are private lands, too. So, be very sure you follow the directions to request online permission to the right area, read / follow all of the ranch rules to the letter, print the maps of the HMA you're hunting, print/sign/carry on your person at all times the signed (your signature) permission slip and post the bottom of the slip from your rearview mirror when your hunting on that private land.

It's a privilege not a right to hunt on HMAs or any private/public lands. Treat it at such, follow the rules and you and everyone else should be able to enjoy that privilige for years to come.
