I inquired about it. Here's the response:
"They do offer CrossFit at Ellsworth, but it is not free as it is here.
There is also a box in Rapid City... http://blackhillscrossfit.com/
If she links up with Minda (HAWC) she might be able to work with her at the
HAWC...Minda is setup with some stuff there."
FYI: Minda's husband is one of the trainers/coaches here at CF Spangdahlem. He's the one who responded to me. Minda is the exercise physiologist at Ellsworth and she was a big part of starting our slice of CF here, as well.
Hope that helps.
