TITLE: Underage Consumption at college tailgate
POST: I'm 19 years old and I live in South Dakota. Was at a tailgate and a police officer asked me to take a breathalyser test because I was holding a 21 year old wristband. Not wearing it on my wrist I was just holding it. I refused to take a breathalyser and he gave me a ticket for underage consumption because he smelled beer coming from my breath. Which I think is kinda ridiculous because there were obviously beer cans all around us and beer all over the ground. 

Anyway I got a court date and I plan on going and paying the ticket and taking alcohol classes or doing community service hoping it gets erased from my record. But I was just wondering is there anyway to get it dropped because the cops only evidence was that he smelled beer from me. I was not holding any alcohol. I was not acting belligerent, there was no reason to suspect I was drunk or drinking. I was being respectful to the cop. And I'm just really bummed this was how I got an underage when i wasn't even drunk.
TL;DR: 
got a underage consumption, is there a way to fight it/get it dropped? If not what is the best thing to do when I go to court?
