[Land-speed] Need museum suggestions for Indy.

[Wester Potter]

I'm driving from  Champaign, IL and flying out of Indianapolis next Monday
evening.  I will have a rental car I'll have to return by six.  I intend to
visit the Speedway Museum again that afternoon.  What other museums are within
a convenient driving distance?  I've done the ACD Museum in Auburn, IN a
couple of times and it's just a bit out of my way.  I would appreciate
suggestions for any other spots I should see.
