"John Robitaille" Wing Shooting

Wing Shooting in Wyoming

As an avid bird hunter, I believe the Grey Reef Ranch is as good as it gets.  I’ve been hunting the “Ranch” for several years, and have found the cover for the birds to be in outstanding condition, the birds themselves are big and healthy (and act very similar to wild birds), and the proximity to water is ideal for my dogs.  I have trained young dogs and worked older dogs with great success. 

Whenever I get an opportunity, I recommend the Grey Reef Ranch and Crazy Rainbow Wing Shooting to all my bird hunting friends.  If you want to hunt with a knowledgeable guide, the Ranch’s experienced dogs, or on your own with your own dogs, there is always extra space and plenty of birds hiding in outstanding cover at the Grey Reef Ranch – they’ve got it all.  Why travel to other destinations when we’ve got great wing shooting right here in Casper?

"Mike Chauvet" Cast & Blast with Crazy Rainbow

Cast and Blast in Wyoming

I wanted to let you know how much we enjoyed our hunting / fishing trip. The accommodations were wonderful, there were hundreds of antelope, the fishing was great and the scenery was just spectacular. Everyone had a great time.

Crazy Rainbow is a first class operation. All of the people and guides were very accommodating. In addition to the normal duties, each of them went above and beyond. From Bob at the fly shop calling to let me know our bows arrived at the shop, to Chad calling to let us know when we needed to apply for our antelope and elk tags.

I was beside my son when he harvested his first antelope. Priceless.  I do not know how else to describe it.

I cannot say enough about Jon Keil and Chad Berens. They know hunting and fishing and did everything they could to make our trip successful and enjoyable. In addition to their hard work and guiding abilities, they are great people and I really enjoyed getting to know them.

Thank you for all your help in making this a great trip for all of us!
