Ah, contests -- the place to see the best and worst things about our hobby.
I've been involved in many, many contests -- everything from IPMS Nationals down to mall and hobby shop contests. I have judged with IPMS rules, AMPS rules, Chicago rules and no rules. I've also been involved in NNL-type shows. All (except "no rules") have plusses and minuses.
Don't let a bad experience or two sour you from attending contests. If all you are worried about is winning or losing, you will likely be disappointed. If you go to a show with the attitude of learning and expanding your experience, you wil have a better time. This is a rather solitary hobby -- before the Internet, clubs, contests and shows were the only places modelers could get together and share their love of the hobby. Go and enjoy -- and let the medals and ribbons fall where they may.
One contest "war story" -- the Kansas City area has several model contests each year. One year, our local club in Leavenworth hosted a contest in which we used a modified IPMS system -- and we had LOTs of added categories, especially for car and truck models. One modeler, who we nicknamed "the Whiner," came in right before entries closed, scouted the room, then went out to his car trunk to pull out models to enter in categories that had few or no entries -- thus "ensuring" he would win something.
Well, the Whiner's stuff was awful -- glue smudges, THICK dust, fingerprints, silvered decals, runny paint jobs, no attempt to fill gaps or sand seams, many models not painted at all, broken and missing parts ... you get the picture. Now this guy wasn't a newbie or disabled -- he was just lazy. A couple of his models managed thirds, but most were just too awful to reward with a ribbon. A few of the judges thought we shouldn't shut out his models, no matter how bad they were, but the majority ruled -- we based the decision on the basics of model building, which is the first consideration in IPMS judging.
All through the show, the Whiner and his girlfriend roamed the contest room lobbying judges and promoting his stuff to anyone else who would listen. They never praised another modeler's work, never asked a question, never tried to interact with other modelers ... in fact, they seemed to take great delight in pointing out comparatively minor problems on other people's models, especially the junior entries. The kicker came when we counted the "People's Choice" ballots and realized that he and his girlfriend had stuffed the ballot box.
When the awards were passed out, the Whiner and his lady friend became loud, profane and argumentative. Our head judge tried to tactfully explain things, but they wouldn't hear it. Whiner and friend scooped up all their models, threw them all in a big box and dumped them in the trunk of the car. In the process, they managed to damage a few other people's models and insult just about everyone.
In retrospect, I can't help but wonder how many people -- some attending a model contest for the first time -- had their opinion soured by this jerk's actions.
