Crazy Salt, great question!

It's made by "Janes Krazy Mixed-Up Seasonings", the real name is: Janes Krazy Original Mixed-Up Salt.

(There is also Krazy Pepper, great for rubbing on fish, I love it on Stripped Bass)

Anyway, the back of the container says it's distributed by Flavor Delite, Inc in Richburg, SC. I get it at the local Stop & Shop or Shaw's Supermarket. I think it's been around since dirt. I found a website with a photo of the container if you want to find it in stores:

In general, any of the spice blends would dramatically improve small game, this was just what I was always able to grab out of mom's cupboard as a young buck heading out into the world. Once I was out on my own, I guess I just had made it a habit. Try this stuff when you make home fries... to die for on an old iron skillet over a nice bed of hardwood coals on your morning cooking fire. Yummm.
