Jdang, It sounds like Crystal Mountain will be right up your alley. Plenty of mellow stuff for your wife, but also plenty of gnarly stuff for you. And it's all close together. Snoqulamie will also be great for your wife, but not as great for you, unless you really like park, or can leave her on the west/central/east side while you go to Alpental. Stevens is another option, but it's a bit gnarlier for your wife. No matter what though, they will all have places that you both enjoy. And if you get to Baker, just make it on a powder dump day, then maybe you can get your wife into some gnarlier stuff without the fear of major breakage.
