FYI, I just checked the Colo regs and the "2nd season" is from 10/21 - 29, not the 19th. Just so's you know. I can't see any advantage to putting in for a draw in those units.
Looks like you are hunting either unit 61 or 62.Lots of good advice above, not going to rehash. BUT! the most imortant advice was to dress in layers! October in the mountains can provide snow or heavy frost at dawn, and sun screen weather by early afternoon. Some equiptment Idon't go without:
A big gun (.300 WM is my pic), and practice long shots (200 yards +).A game cart &/or a backpack frame (for getting the critter out of the woods, assuming you are successfull). Lightweight waterproof boots, more like hiking boots than hunting boots. First aid kit. Good sharp knives and a small game saw called a Wyoming saw. Slices right through the breast plate and bones for quartering. Remember, a 1/4 Elk can weigh as much as one of your Texas whitetails.
One thing you NEVER want to bring or wear, are any outter clothing like Carhart's! That brown color can make you look exactly like an Elk!
As far as the hunter orange deal:
"It is unlawful to not wear at least 500 square inches of solid (camouflage orange is not legal; mesh garments are legal, but not recommended) daylight FLUORESCENT ORANGE material in an outer garment above the waist, part of which must be a hat or head covering visible from all directions while hunting deer, elk or antelope during any muzzleloading rifle or rifle seasons. BOW HUNTERS ARE NOT REQUIRED TO WEAR ORANGE DURING THE ARCHERY ONLY SEASONS."[/align]Good luck![/align]
