On my first solo mule deer hunt, I got skunked. I didn’t even see a shooter buck.

I’d done my homework, scouted the area, and even saw signs of some respectable deer. But after a week, the final score was Mulies 1, Me 0.

During the six-hour drive home, I pondered the hunt, trying to figure out what I’d done wrong. I vowed to learn from experience by talking to some experts.

What I learned from them was eye-opening. Although I’d managed to avoid some of the worst mistakes, I did make my share.

Most hunters commit mistakes that can be grouped into seven broad categories. Avoiding any one of them might automatically prevent others. Avoid them all, and you’re more likely to have venison for supper.

1. FAILURE TO PREPARE
The worst mistakes are made before hunters even leave home, simply because they didn’t study in advance.

• Like a knife in a gunfight. Mule-deer country ranges from high desert and sagebrush to heavy timber. Too often, guides greet clients who don’t bring the right gear for either.

“Most often, I see guys come without good optics,” said Dale Denne, with BearPaw Outfitters in the state of Washington. “If you don’t have good optics that you can stare through comfortably for hours, you’re just handicapping yourself.”

Many first-timers also arrive without the proper footwear for steep terrain and clothing for the weather.

Finally, unbelievable as it sounds, many hunters bring the wrong kind of firearm or ammunition.

“Some of these deer dress out at 250 pounds,” said Mark Paul of Lassen Gun & Guide, in California. “They’re big animals. You can’t assume lighter bullets that work on blacktails will do the job. Mule deer are just a different ballgame.”

• You’re a stranger. Assuming you’ve done enough homework to pick an area with a recent reputation for big bucks, knowing the country intimately ensures that you’ll hunt the area better.

“You need to be set up in your spot, ready to hunt, at O-dark-thirty because you may only have 15 or 30 minutes of morning light before bucks bed down,” said Jeff Zennie of Zennie Outfitters in Oregon.

“You need to know how to get where you need to be in the dark. It’s better to be two hours early than one minute late.”

Careful study of good topo maps, plus phone calls to game wardens and wildlife biologists in the area, are obvious assets that will improve your odds of finding deer. But hunting them requires pre-season scouting. It reveals secrets of the land -- like how the wind shifts as the sun rises -- that you can use to better plan your hunt.

• You’re out of shape. Hunting mule deer usually means trekking long distances, and almost always uphill. It means spotting a deer a mile or more away and double-timing it across hills and ravines to get close enough for a shot.

It means navigating through thick brush or forest. And if you’re not in shape for any of that, you’re just not likely to see any deer.

“We may scout an area all summer and see some great bucks,” Paul said. “But if a hunter isn’t in condition to get up there and doesn’t want to go, we’re compelled to go somewhere we haven’t spent as much time scouting.”

The alternative to getting in shape, of course, is just to drive along the roads and hope for the best. Good luck with that!

• Great expectations. Along with knowing the area, you need to know what kind of bucks it produces and what it takes to get them.
