Mcfish has the right idea, the nearest gas station would be $. Those machines are all over in TN and VA and I am sure a good business opportunity for someone with the startup investment money heere in CO. I have never seen one with minnows. Only nightcrawlers, bloodworms, leeches, crickets, and red wigglers. Near the coast in NC they also have peeler crabs and clam bait in those things. Good luck, Just make sure you keep the product fresh for a while so that people know they can count on that machine for their bait. Repeat business is the key! Let me know where you put it. If it is anywhere in the state I am sure I pass it a few times a year.
