@AJRSki Afton is a great place to learn. They have several programs for adults. Two you may want to consider are: Men's Academy, it's for men only with male instructors and the primary focus is to help the individual improve their skiing efficiency; next is Get Ready For The West, it's primary focus is to help the individual expand their skiing terrain so they are more comfortable out west. (BTW, there is also a Women's Academy.)
There is also All You Can Eat Gates which is race practice for the general public but it includes coaching.

Several people have mentioned getting comfortable skiing moguls. This is great training for out west. You mentioned you want to ski steeps out west. Most of the steep runs and Black and Double Black runs out west are mogul runs. Most steep lessons out west are really mogul lessons because that's really what you'll be skiing.
Peak 6 at Breckenridge is mostly a Blue area but it is always covered in moguls. To ski moguls well you need to work on your technique, primarily rotary. Get really, really good at pivot slips and you will be able to ski moguls. You don't learn or practice pivot slips in a mogul field, you do it on a groomed run with a moderate pitch.

Afton has a boat load of great instructors that would love to help you improve your skiing. If you want to train for out west and powder skiing try to hook up with Tom Fontana at Afton. Tom is a PSIA Level 3 instructor and is 70 years old. Don't let his age put you off because two years ago he got his Million Vertical Feet parka from Canadian Mountain Holidays. He knows how to ski powder and is always looking for a buddy on his spring heli trips.
Since you live in the twin cities area you have another resource available to you. The Alpine Factory,
https://thealpinefactory.com.
It's a indoor revolving infinite slope, one of the few in the country. It's a fantastic training tool and a great place to perfect your technique. The owners Jessica and Dan are both PSIA Level 3 instructors. They also have a young man on staff named Joe Kagan. Joe is only 20 years old, is also a PSIA Level 3 instructor, is already on the PSIA Central Division Ed Staff and is a really great instructor.
Regardless of where you decide to ski take some lessons. You're the kind of student instructors live for.
