John,

Try expliciting specifying the projection info for your layer(s) instead.
This tends to work when epsg codes do not.... 

Here's my template for doing this:

   PROJECTION
           "proj=lcc" #projection name
           "ellps=GRS80" #aka spheroid
           "lat_0=63" #lat of false origin
           "lat_1=49" #lat of first stp
           "lat_2=77" #lat of second stp
           "lon_0=-91.86660000" #lon of false origin
           "+x_0=6200000" #false origin easting
           "+y_0=2958000" #false origin northin
   END

Thanks to everyone helping me to find the EPSG code, I was able to find both
the esri and epsg file in the proj directory.

Unfortunately, I had the epsg code correct (I was hoping it was wrong,
because the projection isn't working).  I'm trying to get a shapefile of the
Midwest states to work with a projected tiger county (epsg:26930).  I'm
including the prj file for both the states and my county, along with a
mapfile and an image of what I'm getting.

I've been reading and searching, and I thought this should work, but my
north Alabama county is winding up in Maine.

Any help would be appreciated.

Thanks,

John Cole
