This is/was a very solitary hobby. That makes the shows very important to me. The online forums have helped somewhat, but, I like the walking around and talking with other modelers. Even if I didn't do something "wrong" during that year, someone else probably did, and you can find him talking about it.
There is a sort of unwritten code that we don't outright trash a manufacturer's product online or in print,,,,,,,,but, when you are talking to an actual modeling friend in person, that is when you can learn something that saves you money. Learning isn't always about eliminating a seam, or learning how to thin your brand of paint,,,,sometimes it is about what decals won't even come off the backing paper, or what paint won't stick to primered plastic.
Competing can build your skill level, if you are really trying to someday win a 1st or Gold, in some builders you can see the progression from no medal, to Bronze (3rd), and up to hopefully celebrating a 1st with him someday. (I have a friend that has gone from "Rex's level" up to Bronze and Silver. If you never enter a model, you will never know just how well you really build.
Me? "Award winning modeler?",,,,,,,yeah, if they start giving out 4th places, or introduce the Copper and Lead medal, lol. Someday, though, maybe,,,,,,I know that attending the shows has shown results in my models already, even without winning the hardware. Just the attempt to improve makes one improve.
Jim, I am with you,,,,,,,,,if all I ever win is a Bronze/3rd I will be happy.
