NAD 83 -- 30:16:28.82N, 97:44:25.19W --or-- 30d16m28.77992N, 97d44m25.10907s
NAD-27 -- 30:16:28.03N, 97:44:24.09W
WGS-72 -- 30:16:28.68N, 97:44:25.75W
Interesting because using the USGS "Corpscon" conversion tool, I entered the NAD27 position and asked for the NAD83 position, which as you can see differs from the ones that the Texans found. Question being, did they read a map and measure from it? Or convert datums, using a formula different from the one the USPS supplied?<G>
