I gut my First Deer myself back in 1989... Just took me Hand's on experience. I knew I could do it... and of course I've got better as the year's have gone by. But I was able to Gut my first Deer myself... not real hard.
I just make it a point to Gut the Deer right away, and keep from cutting into the Paunch, and Bladder... and watch the Poop too. That Spike I got this year was so fiull... it was really tricky getting them out, without getting on the Meat. Some Deer is easier if they've peed and pooped recently.
