Can’t say I’ve ever been to a concert that seemed so unprepared to sell beer. Half of the concessions closed before the opening act even started, and the remaining concessions ran out of beer multiple times. Lines were insanely long, and supply did not meet demand. Venue was cool and the show was great, but the supply chain on beers was not.

Here for multiple dog shows for a week. This is a great venue for shows. Plenty of parking and entrances. Lacking handicap spots for exhibitors. RV spaces with full hookups. Restrooms are maintained. Parking was $10 for each day of entry. Credit/Debit cards only. No cash!!

Great space for conventions and events with large crowds.

Not being from this area I didn't know what a Brat was and although there were hundreds of people eating them I didn't buy one I was told it was a cross between a hot dog and a sausage but the atmosphere was awesome there was a lot of activity going on it's just a good afternoon

This is a large place. First time ever being here. I took my husband for a surprise road trip. He loves to fish. I hate it lol someone's you have to do something for the other person. There's plenty of restrooms available. Food areas with sitting area. Large conference rooms and plenty of them. Large parking lot which for this event you had to pay. Not sure if that's for all events. It was a great experience.
