[postgis-users] couldn't get the correct projected values

[Don]

I am having problems with Transform. It is giving me values which don't 
seem correct.
This command transforms nad27 clrk66 to UTMzone16 grs80 nad83 meters:

select AsText(Transform(GeomFromText('Point( -85.70285 35.50463)', 
4267),'26916')) from table;

I get what seems like a reasonable value.
POINT(617641.061533109 3929788.38473634)

However if I run this command:

select AsText(Transform(GeomFromText('Point( -85.70285 35.50463)', 
2204),'26916')) from table;

 I get this result:
POINT(-17819.6295321235 3799331.7285575)
This does not look like a valid UTM coordinate.  I thought that they 
were offset so that they are positive.

SRID 2202 is defined as
"+proj=lcc +lat_1=35.25 +lat_2=36.41666666666666 
+lat_0=34.66666666666666 +lon_0=-86 +x_0=609601.2192024384
