If I may, While the person who posted the negative comment was banned, I feel the need to tell you what your gallery has done for me.
Growing up my parents didn't have a lot of money. My dad often held 2 or 3 jobs to make ends meet. My grandfather was quite aware of my passion for trains and gave me some of the locomotives I see here. Through the years they have either been mis-placed or handed down to nieces or nephews. Your gallery sir, was refreshing to me, it invoked memories of what life is all about. I thank you and encourage you to keep posting as there are still quite a few of the 'good guys' still out here.
