I hear ya Al, I also have a notebook full of ideas for future builds that I don't have kits for to start..... I have note cards in the boxes to know where it was headin', or a photo of the real car or what ever to keep it on track....
Must be the A.D.D. in me 'cause I can't work on one at a time. I jump between two and sometimes up to five or six at a time just to keep things moving along on them. Must be why I have around 50 started kits right now!!!!!
