My wife is the Greatest Woman Who Ever Lived! Not only does she support me in the O gauge hobby, she encourages it. She is a great enabler on the layout we are building.
She also has hobbies that I encourage and support. Her biggest is genealogy. I've spent many a trip walking through old cemeteries looking for ancient relatives and spent many hours with her in small libraries in small midwestern towns. But it's a small price to pay, and really pretty interesting what she's found, for all the support she provides for the train hobby. She has even found connections with relatives and trains! Some day she wants to create a book with all the info she's uncovered to give to our grandchildren to learn where they've come from.
With the trains, not only does she let me buy anything I want, she will sometimes buy trains that she likes along with scenery and buildings. What's more, she occasionally will surprise me with railfanning weekends to the PRR Horseshoe Curve and the surrounding area and sometimes will ask me to stop while we are driving at the old train station in Elkton, Md. to watch Amtrak trains fly by. She happily attends any social model or real train function with me. On a recent family reunion trip to Georgia, we stopped on the way home at the Aiken, SC. Train Museum and the North Carolina Transportation Museum and took the train ride and walked the grounds and exhibits while she took bunches of pictures.
AND, she's an awesome cook! All that and she's a sports fan, going to many baseball, hockey, football and basketball games with me.
