You know, I am not sure how far they roam in the northern part of the state, they are everywhere in the southern part of the state. I really only know areas around Tucson and I'm sure they everywhere around Phoenix. I would recomend the units around Tucson units 33, 34 ab, 36 ab, and 37.
The draw odds can be found at the AZ game and fish website, the odds are good.
The good thing about hunting them with a bow, the season is all of Jan and you can purchase a deer tag over the counter also. Deer and Javillia live in the same area.
Hope this helps.
