Replying to Liquor ticket

So I'm from Canada, and me and 3 of my buddies got a liquor ticket in kentucky. Anyways, I'm now back in Canada, and I'd have to send the money through mail to pay the ticket. If I had no intentions of going back to the states ever, I would definitely just say fuck it and not pay the ticket, but that's not the case. So if I never paid the ticket, could it cause a problem for me at the border if I went back, or do liquor citations never even leave the state? The police officer said if we don't pay the ticket, a US marshal would come after us, which I know is bullshit, but that made me think whether or not this would come up at the border if I tried to ever go back in.
