Thank you Harry, Pat, Bob, And Dave!! I think all of you are correct! I think it is a good plan for someone who wants to tun trains somewhat simulating a prototypical manner, in limited space and leave room for interesting scenery. This was my thought a couple weeks ago, but I wanted to give reasonable suggestions some consideration. Dave gave me a suggestion offline that may aid in having cars ready to swap out quickly when making up new trains, that I will give some thought.
I am glad the discussion came up on the window to the laundry. Since we bought the house, we have kept the window open to let some heat from the vent right above the washer into our daughter's art room. I never thought about moisture getting in there, and daughter certainly would have raised the issue if it had affected her variety of artworks and materials. My wife and I both thought I may want to take the window out altogether. We have never used that baseboard heater on the far wall. I don't think I should have a problem with moisture especially if I have the dehumidifier running. Does anyone have any thoughts on that.
Other than that, I am ready to get some wood and have been looking at miter saws at Lowes and Home Depot. I recall a suggestion for a compound one. Progress may be slow for now, but I should be able to make progress over the summer.
Thank you everyone!!
