Go to U-Pick-EM Minnows, the minnows at conoco are very very small and not worth buying..
U-Pick'Em Minnows 307-272-2679 Jackie or 307-272-4769 House, give them a call to make sure they will be around when you need minnows, since sometimes they are out checking their traps. They will get up most days at 06:30 a.m. if you call and let them know you want to get them that early....
