Went there for the 90s flannel fest. Definetly the best tributes bands festival and the best place to enjoy a music show. I loved Linger the Cranberries tribute!

I had such a great time at the Grant County Fairgrounds with my family. It’s very family-friendly, and my kids especially loved the petting areas with so many animals to interact with. The clean washing stations right outside made it super easy and comfortable for us. We also enjoyed trying the wide variety of food options—there was something for everyone. The owners and staff were incredibly friendly and welcoming, which made the whole experience even better. Between the rides, games, and other activities, we had plenty of ways to spend quality time together. The rodeo was definitely a highlight, and the friendly horses were amazing to watch. Overall, it was a fun-filled day we’ll definitely want to repeat. Highly recommend! And respect to the officers on duty and thankful everyday for everything they do!

The place is nice. We arrived very late at night, and it was a quiet night. We understand and respect that the person in charge of mowing the lawn was doing his job. However, we needed to work, and the noise of the machine made it impossible.

Such a cute little fair ground. Seriously gives off charlotte’s web vibes. Very well kept. Bathrooms are clean. Sand is nice to ride on. Has campground and showers. Even Ronald Reagan’s signature.

Amazing place, the gun show rocks big time, come and support the locals and get some awesome goddies... guns, purse, earing,coffee, decals, t shirts, camping gear, and more. Restrooms available super clean, lots of parking, bring the whole family... munchies and drinks available and the entry fee is valid for 2 days. Lots of collection guns for sale at a really good price. Ps. Do not bring guns and do not bring your pets.
