Kamil,
Late Oct. here in southern AZ is still fairly warm and you should bring light weight clothing but as all ways come prepared for rain and cooler weather. Are you going to be using a guide service? If so then they can really tell you what type of camo works best for that region. You can also get lots of information form the AZGFD at their web site
WWW.AZGFD.com and there is a local site that you can go to that may be of some help try
WWW.AZOD.com and go into the forum/chat area. I’ll try and get some more info on terrain and camo that works best in that area and post it here for you.
Good luck…
PS: Google this and you will get lots of info as well
