Well, I finally got the urge to go to the hobby shop to look at some trains. It was a delightful experience with its good and its bad. I was completely amazed at the details to some of the engines. The nice clerk there happily assisted me with my questions and showed me the different classifications of trains. I never seen those smaller scale trains first hand, until today. I was shocked to see the N-scale, of how small it was when the guy showed me. Then he shows me Z-scale, I was like..., after not really recovering from the size of the N-scale. (Note: I couldnt find a with bigger eyes in the edit box here). Then I asked them about the prices......!!!!!! I hope this explains my reaction, no?? There was this beautiful, highly detailed, steam locomotive, I forget if it was HO or N, but I do remember being $750! Anyho, there were like diesel locomotives for like $50 - $150. And I thought my rc airplane hobby was expensive. All in all, I had an enjoyable morning for the most part. I also have some serious thinking to do and a lot more research to do as well.
