Based on the video context provided, it is unclear where the biggest bass was caught. In the first video by Milliken Fishing, they mention fishing at a location called Sandy Lake, which is 16 hours away from Minneapolis. However, they do not specify the state or region where Sandy Lake is located. In the second video by Jon B., they mention fishing in Texas and catching a ShareLunker bass, which is any bass over 13 pounds caught in Texas between October and April. However, they do not specify the exact location within Texas.
To determine the specific location where the biggest bass was caught, more information is needed. It would be helpful to know the state or region where Sandy Lake is located in the first video, or the specific lake or body of water in Texas where the ShareLunker bass was caught in the second video.
