$3 Grinder, this site, deer processed in 2 1/2 hrs

Thanks to my wife and the $3 grinder she found at our local Goodwill store, we decided to process our own deer. It's been decades since I helped with the butchering (I grew up on a dairy farm in northern Indiana). In the past few years, I've become very dissatisfied with the quality of deer processing. Don't get me wrong, some have been great but they're close to 2 hours away. My main issue has been the concern over not getting my own deer back and not enough meat. Some processors have yielded barely 20% of the field dressed deer. My processing yielded over 30% and that is with some waste from the "shot" area.
This has been a great experience. Thanks Woody and others on here for some great information. My crude processing job took a little time since I was not in a hurry. My wife and I are pretty simple when it comes to our deer processing preference. We simply save the tenderloins, backstraps (or loins), and grind the rest to be used in casseroles, spaghetti, etc. The skinning and "chunking" which I did myself took 1 1/2 hours. The grinding, packaging, and cleanup, with my wife's help took another hour for a total of 2 1/2 hours.
Once again - THANKS to all on here for some great information, tutorials, and pics.
