Welcome to the Guild, David1961.
Post one of you older maps - we'd like to see what you've done! Use the paper clip and at your map as an attachment.
If you want to stick with free Inkscape and GIMP are among the best and are free, but can be tough apps to learn - good tutorials here for them, but still tough for new users. Not many Autorealm fans here, I'm afraid. Good luck in your quest to finding what best works for you.
