I'm entering my first contest in march. I was going to compete under the teenage section but I already know I can win that given the competition from previous years. I'm 18, and the other 2 groups are mens open, and mens novice. My question is what is the difference between the two? can either group win the entire show? I guess someone from the teen section couldnt win the whole show could they? Newbie question, sorry vets if it sounds dumb.
