"Open 24 hours, gasoline and diesel, saved me from running out in the middle of nowhere"

"saved a friend when they ran out of gas."

"The entire team @ Bison Grain Coop were friendly and extremely responsive in my time if need. I ended up with a truck issue in a very remote section of the Greater Bison Territory and once I was in cell phone range I rang the Coop and they knew right where I was and helped get my vehicle back operational in less than an hours time! No exorbitant cost, just straight talk and an honest rate. Many Thanks to Bison Grain Coop for uphold the Value of Trusted Neighborhood Business and Friend! Much Respect, Jolly Goodfellow Colonel (ret) USSF"

"Genuinely the best experience I have ever had at a gas station/service center with some of the friendliest people I’ve ever met. I go out of my way to go here any time I am anywhere near Bison to fill up. The most recent time I was in, I was having issues handling my car and asked Kortney there for advice and she checked my tires and washed them out for me as well as gave me advice if I have any more issues. I could not more highly recommend stopping here. Also! She told me that while google says they’re not open Sundays, they actually are open 7 days a week and have someone there until 7am-10pm everyday and they’ll soon be open 24 hours."

"Douglas at the truck repair shop was helpful and friendly enough, which is why 3 stars instead of 2...he had originally talked us thru some electrical issues over the phone on Saturday. Well Monday we came in with problem unresolved. He did some electrical testing and sold us a new brake controller. I asked about the wiring under the camper. He didn't think it was an issue (well it was). We had issues 100 miles later and on (which finally got resolved in Gillette Wy)."
