It is possible to hunt both, but i would not do it. I hunted unit 93 in 2012 and found a lot of antelope near Fontanelle Res. area and never saw a deer. I think you would need to move camp into the Wyoming range to get into better deer country. I would focus on one animal at a time and make the most of your points and enjoy the hunt. Having two tags in your pocket can put unwanted pressure on a hunter. It will be many years before you can hunt that area again for deer and antelope.
