I don't concern myself with whether something will be around in the future. Times change, and with them, so do interests. I just enjoy what is available now, and thank the Plastic Gods that it is available. I do what I can to promote the hobby, and steer clear of any talk or actions that might lead others to thinking that this is a "nowhere bound" hobby. The best way to encourage others to enter the hobby, and therefore, assure a future for it, is to refer to it in a positive manner. I thank the model companies for not giving up on us, and for their renewed vigor, I also thank those that supply forums for us to share our work, which is probably one of the biggest assets in the revival of the hobby. I appreciate those that not only share their models with us, but share the build process, allowing us to learn new techniques.
You see, it takes everybody working together to keep a hobby alive. We have that now. Enjoy it while it's here.
