I concur with Rallybum.
ABQ - If you have not seen the Balloon Fiesta, you have missed out on a very unique event. I flew the fiesta for nine years, and even as a participant, there were times where I would just take a look around and say "wow"!
The big issue for you would be trying to secure accommodations and a rental car. The Double Eagle Airport is just across the street, but I do not know if you can get a rental car there. Back in a past life, I used to fly a GA plane into KABQ, and the FBO's were always very accommodating to us.
When you are done there, it is a short flight to KSAF or just use your rental to drive.
Mount Rushmore - Fly into KCUT (Custer County) and arrange for a rental car. You can stay in Custer if you wish as it is closer to the airport (try the Dakota Cowboy for a great breakfast), but my wife and I recommend that you drive to Keystone for lodging. Neat western town with great hotels and restaurants. It is very close to Mt. Rushmore and Custer State Park. You would pass the Crazy Horse Memorial on the way to Keystone, don't miss this during your stay.
Make sure you make time to talk with the KCUT airport mgr, Ralph. He is a great guy, AOPA and EAA member. Ask to see his Stinson restoration project as he is doing a stellar job.
Feel free to PM or email me if you would like more info on either of these places.

Another suggestion would be Mt. Rushmore (a bit more north then you were thinking)?
