Aerobatic training in MN?

Anyone know of any aerobatic training within a reasonable -7 flight from KAXN? I would prefer to use my RV-7, but I don't have the jettison installed so I'm not sure if that would be a put off to CFI's? I also don't own or have access to a parachute. Just looking for the skills to do simple maneuvers and enough spin training to save my bacon if i botch them.

Thanks!

I believe Mike Wiskus teaches at the Buffalo, MN airport (KCFE). Try:

The IAC also has a list here:
