You guys are exactly right. As a sign painter you can adapt with the times or close your doors to the young punk down the block who has no skill but knows how to work a computer(dont get me wrong I know the computer takes skill too). But the sign painter that has accepted the computer gets to keep working when the power goes out or the computer hard drive takes a dump or the plotter freaks out.
My dad was a sign painter that got to see vinyl come and take over the world. He would tell me how happy he was that I wanted to learn his trade but to keep an open mind to new things. Thats why today I can sell, do vinyl, design, paint, hand letter, fabricate, install, make neon, survey, etc. I have made it a point to learn as many aspects to the business as I can to keep me working. But I never forget what I knew first because sure enough someone will ask me if I know someone. I get to say 'well sure I know someone'.
