On page 25 of the v6 MEAP:

"We know our projection to be NAD 83 Lon Lat so we indicate this by changing the SRID to 4269. Be careful here! We're simply telling the importer what the SRID is..."

A light rephrase to clarify that we are just *labeling*:

"We know our projection to be "NAD 83 Lon Lat" (1) so we indicate this by setting the SRID to 4269 (which happens to be the code for "NAD 83" (2)).

(2): Check it out by running SELECT srid, srtext FROM spatial_ref_sys WHERE srtext ILIKE '%NAD83%' and srid > 4000
