Hey! 👋👋 Justin, Mara and Jamie here! Now that we have officially dug the farm out of a giant snow bank and had 4 minutes to breath; we need to chat with you guys!

First off, we’d like to thank Mother Nature for making fools out of us. What goobers we are for thinking we would have a 50 degree sunny sale day. Instead, we woke up to ice, blowing snow and wind gusts over 50mph. Justin made the tough decision to continue on with the sale and you all proved to us that he made the right choice.

To everyone that braved the storm and attended and to those that purchased bulls or heifers…. Thank You! We wouldn’t be here without you guys. The trust you have instilled in our program is appreciated beyond words. Thank you for believing in and appreciating Justin Hart’s program. Thank you for supporting my mom (Mara Hart) and dad’s legacy. Thank you for reading along and listening to my ridiculous marketing ideas. You guys are the real MVPs and we know a “Thank you” isn’t enough.

Didn’t get a bull? We are working to put together our private treaty bull list as we speak. Message us with any questions.

Thank you so much again and we can’t wait to see how these boys and girls perform for your operation. 💙💙

Calling all men who are in the dog house! ‼️ It’s the day after Valentine’s Day and you didn’t get your lovely lady a gift. We get it! You’re busy calving, doing chores, and searching for your next herd bull or replacement heifer and it slipped your mind and she’s upset!❤️🌹

Well do we have a solution for you! Let us introduce you to our sweetheart Miss Luna 039N (Lot 71) (ASA #4511792). What’s not to love about this adorable gal! Her dad, Hart Jaw Breaker 058K who goes back to Hart Candy Man 470H produced one impressive daughter here! Her mom Hart Miss 193D is an attention grabber! This 9 year old cow has given us some beautiful babies (WW Ratio- 7@100
YW Ratio- 6@101).

So ditch the late chocolate and flowers! Luna is the ultimate gift purchase to turn your ladies frown upside down. It’s a win-win; she gets this darling heifer and you get a stellar replacement heifer that’s sure to give you the calves you’re looking for. Grab your mud boots and head to the ranch. She sells Wednesday!

Look at that face! 💙🔥 (actual relationship advice from Hart Simmentals is not professionally recommended) ❤️
