Quiet water and the right people can make any day feel just right.

I only use bobbers when steelhead fishing, but they cancelled the season this year. Great bass year and still catching them. Not as many as the summertime, but all the dinks are inactive now, so the bigger breeding bass are feeding up for the winter. Still time for a trip.www

Mah-Hah Adventures owner John Weisner with his 2026 Eastern Oregon mule deer.

After spending much of the season helping others fill their tag, John blocked off the second weekend of the season to do a little hunting of his own. John connected on this buck at 280 yards with a 6.5 PRC from MOA Ri**es

This was a great deer season out here on the ranch!

Mah-Hah Adventures offers a limited number of guided deer hunts each year. These opportunities are kept limited, with availability by inquiry only.

Sometimes everything just comes together. This incredible 7x5 Oregon Mule deer showed up on camera only a few days before the season. As fate would have it, the buck was located on opening morning, and after a hunt that nearly broke our hearts, .weisner was able to harvest the buck of a lifetime at 450 yards with a 7 PRC.

Thanks to our guide partner Zach AOA Outfitters for helping close the deal.

Mah-Hah Adventures intentionally keeps our guided big-game opportunities limited and separate from private family hunting throughout the season. While this incredible deer was taken on a family hunt, a select number of guided deer hunts are available by inquiry only.

Sometimes the best part of a day on the John Day isn’t what you catch.

It’s this.

The canyon. The quiet. The river winding through it all. A place that feels a whole lot farther away from everything than it actually is.

Fishing is only part of what we do out here. Come see the rest.
