Or... Do a search here for "hide tanning".
The best prices I have ever seen on deer/elk/bear/cougar/antelope/gator tanning was a place highly recommended on this forum. (can't remember the name - I think the place was in Georgia)
If you don't want a green hide (actual color, not metaphorical "green"), it's probably best to send it out. I understand the desire to do it yourself, but I've never seen a successful DIY-tanning operation from one of the kits. They come out green, or start to fall apart within a year.
If you're going to send it out:
For hair-off:
Clean all meat, fat, and flesh from the hide.
Spread a 1/4" to 1/2" layer of fine salt (not iodized, and "table salt" sized granules) on the inside of the hide, and roll it up tightly.
Seal in multiple trash bags. And store in a cool, dry place, away from sunlight, until you can ship it out. (In warm climates, you may have to refrigerate the hide, and get shipped out quickly.)
For hair-on:
Clean all meat, fat, and flesh from the hide.
Roll the hide tightly.
Double, or triple, bag it.
Freeze immediately.
Contact the tanning company, and ask what care measures you need to take (for hair-on, most companies have different preferences for preservation).
-Or-
Call before you go hunting, and take those preservation measures as soon as the hide is cleaned up.
I'm all for doing things myself, but tanning has a steep learning curve (or used to - I haven't even seen a DIY attempt in 12-15 years). If you absolutely want a good hide, send it out. If you're more interested in learning the process, I'm all for trying it at home.
