When a older gentalmen came in and was also getting minnows but instead of a bucket he handed over a zip-lock bag with something inside of it, not sure what it was inside but was white maybe paper towles dry ice i dont know, but has anyone seen or heard of anything like this and the reason or purpose behind it ??
