I agree with Canyon. Find a water source and be there before light. You can also get up on a ridge before light and watch the deer bed down, then setup a stalk. Unit 33 has some decent cous hunting on the back side of Mt Lemmon/Catalina mtns. If you travel down the hill a little closer to San Manuel you will find some decent Muley country as well.
I am going to try and use my ground blind this year up in units 23 or 27 for some turkey/deer hunting this year.
If you do not mind going close to the border you might find less hunters but take the chance of border crosser/border patrol. I always had plenty of deer sightings 36A and 36b.
