I am getting closer but I had to make a pit stop and get something to eat. I will try to get to the hotel before dark. The good news is that one of my stops on the way was very fruitful. I visited the Lego store in Columbus (Easton shopping Center) and (thanks to Jeremy's help) I made some better Lego selections for tops. I also talked to some people about pieces for stems and they gave me an Internet site to check out for specific parts from their stores.
My idea was to set these pieces out and see if anyone shows any interest in making some Lego tops. At least I will enjoy playing with them!!!
