RE: bare necessities of deer hunting...
I'd start with an el-cheapo dragging rope ($5 at WalMart), a reasonably-priced camobackpack ($30'ish)and a decent knife (maybe a Buck - with at least a 3" blade - $30). The knife should be sharp enough to shave some hairs from your arm. Truly, your old fillet knife, or even a toolshop utilityknife would get the job done, but it's nice to have asturdy bladehandy on your belt for easy access. I like the non-folding knives because they don't get funky with hair and fat after field dressing a deer.
Also, One of those el-cheapo plastic disposable flashlights for $2.29 at Wally World will do you wonders, as well. You know, the kind that is shaped like a rectangle that comes in red, blue and other random colors. You should always have a flashlight with you.
Seriously, you don't need allkinds ofjunk to get a deer, especially if you're rifle hunting. All you need is something to carry your lunch/gear in, a rope, a knife and a hunting license. You'll also need a lot of patience, brainpowerand stealth- this is where most guys run afoul.
I'd also make sure that you have a properly (professionally) mounted scope on your rifle, and make sure you pick a scope that is a good match to your rifle (For example, don't put a .22 scope on a 30.06 or a 12 gauge slug gun). The guy at the gunshop will help you out with this.
As for hunting clothes to start off, you'd be fine using hand-me-downs or military BDU's that you got on the cheap. Just layer with sweatpants or whatever you have lying around for warmth. Get a warm, blaze orange hat also. Your clothes don't even have to be camo - guys in blue jeans shoot deer every day. Camo pants are pretty cheap (about $20 anywhere), and are a good investment. You'll also need boots - but your work boots will be fine to start off with, so long as they're warm enough. If you decide to buynew ones, I'd recommend Rocky with 800 gram thinsulate. They are fairly warm/waterproof.
Once you get a taste of hunting, you can move on to treestands, designer camo, ultra-expensive optics, rangefinders, special use apparel/boots, bows, releases, ATV's, monster trucksand custom ammo, but let's not get ahead of ourselves...
If you don't like it, you don't want tofeel like you've invested a ton of money in it, so you can always sell off your rifle and move on. So really, you don't need much to start out. If you have any questions, shoot me an email.
