projection trouble - Michigan GeoRef

[Dylan Keon]

Hi,

I'm trying to use a layer that's projected in the "Michigan GeoRef"
projection, but I can't get it to line up with other data.  I'm using
the projection parameters provided by the state of Michigan
(http://www.michigan.gov/documents/DNR_Map_Proj_and_MI_Georef_Info_20889_7.pdf).

Here's what I get when trying to line up a Michigan layer (GeoRef
projection) with a national 24k quad index (geographic), putting
everything into geographic for now:

I haven't found examples of this online, and wonder if I messed up a
PROJ definition or something.  Thanks for any help.  Mapfile is below.
