"Can one stain 'New' Red Oak to match 'Old' Red Oak?" This is tuff to do. When we do a repair in an old Vancouver Home I often use some Shellac first and then top coat with Polyurethane. The shellac gives me the aged look or yellowing and the two seam to work well together. Some times we tint the top coat a little. Judgement calls since sunlight and time will yellow the top coat so making it look right now might make it look wrong in a year.....

I shouldn't have said cankers, I thought the word cankers was interchangeable with frost crack and sunscald, and now I know that they're not. My trees had frost crack and/or sunscald, due to being planted on the south/southwest part of our house. The trees i planted were susceptible to it, which I didn't know at the time. The Crimson King didn't survive no doubt because I didn't water it enough. I watered it, but it was like 8ft tall, and i only watered it about 5 gallons a week (puny for my fast draining soil). And probably the same could be said for the red rocket maple. But the golden Raintree died during a bitter cold winter. I read it was to zone 5, but most sites have it at zone 6, so it wasn't right for my zone in the first place. Dh and I decided this morning that we're going to do a 6ft L fence blocking the 3 properties that abuts ours, including the next door neighbor, the neighbor's Christmas tree property, and the empty tract of land belonging to his parents. The entire fence will be about 150ft long. That's an immediate 6ft screen. And no waiting for 10 years for conifers to do the job. He's going to take some time off in May or June and we'll do the fence. Just a simple wood fence. No one around here has a fence. Not a single solitary person. But then they don't have 3 properties abutting their backyard either. We're doing an L fence because we don't want to close off our entire back yard. We like the openness to be outside barbecuing and being able to say hello to neighbors walking down to the lake, or the elderly couple who lives up the road, they must be close to 80yrs now, and they walk hand in hand every spring and summer past our house, and then back. I love them. I would hate being fully blocked off from ever seeing them. I admit every spring I look for them, and always a little scared they won't walk anymore. I have 3 Lilacs on that side, and they are quickly growing and will provide some screen, so the yard won't be fully exposed to the road. We also live out in the middle of nowhere, so the only people who drive past here are the people who live here, and the few people who take our road as a short cut to a nearby town. And now, I'll be able to relax and plant what I want, and for no other reason than pure pleasure. Who knew! lol We still plan on planting Junipers and other shrubs, but now they''ll be here and there, for a focal point, not for a screen.

We replaced most of the flooring on our main level with site finished 5" red oak earlier this year (upper level and one room remains 2 1/4"), so I don't have any long term experiences yet. However, I did have some of the same concerns that you have. In my attempt to research, I concluded that the homes that tended to have issues were ones where the 5" hardwoods were installed over a crawlspace. I really like the way our floors turned out, but be aware that the board lengths will be shorter than the narrower width planks. We have not yet repainted, so please ignore the battered paint

If you haven't already purchased your flooring material, I encourage you to reconsider the use of engineered flooring. The increased stability of engineered wood versus solid wood makes it a better choice for wide widths.
