I agree with Ed.  This is a problem, and I remember commenting about it
extensively following the 2000 Census data started being released.
Perhaps there's an opportunity to collectively ask the appropriate
agency/agencies to see if there is a way that professionals can receive
the data prior to or at the same time as the press.  I have since
forgotten about how/why this embargo thing occurs, but it would save us
a lot of time explaining and correcting things after-the- fact.  --Tom

This has always been the issue. The press gets the data early as
embargoed and then the transportation folks get torpedoed and don't have
a chance to respond because they haven't seen the data.  Case in point.
The Atlanta Journal Constitution ran an article about one county leading
the nation with a 51 minute travel time.  Well after the story broke
Joel North from GDOT and Nandu Srinivasan used PUMs to learn the data
looked funny.  There were way too many 150 minute type commutes.  The
data did not make sense and with sampling things can happen.  Elaine
Murakami then found out from Phil that indeed something was wrong.  The
CB had a bad coder survey taker at the front end, going through
retraining and trying to figure out how to deal with the data..  The
point however, is if the "public agency" transportation community had
the data when the press had it we may have been able to inform what
became a very misleading article.

Another point--People do need to look at the data.  I have playing with
the rank of all 775 counties that have data by their mean travel time.
American Factfinder has a lot on it.

Land of the long commute: Georgia is No. 1 in counties with time-wasting
trips to work. The sprawl makes homes affordable, but the crawl drives
down the quality of life.

 How time flies!  Just when you thought you were getting a handle on 
 the journey-to-work data from the 2005 ACS, the next round of data 
 will released!  The next set will include Place of Work tabulations.  
 >From the CTPP world, these are like "CTPP Part 2" tables, where the
tabulation is by
...
  place-of-work, rather than place-of-residence.   Since
the 2005 ACS included
...
  ALL counties in the sample, the place-of-work
tabulations should look 
 much better than the 2004 ACS place-of-work tabulations (about 
 one-third of counties were included in the sample).

 Don't forget:

 1.  2005 ACS does not include Group Quarters population.  That is, 
 areas with large military installations and/or college dormitories 
 should expect considerable differences when comparing to Census 2000 
 results.

 2.  The data are collected over all 12 months, therefore areas with 
 seasonal shifts are likely to see the greatest differences when 
 comparing to Census 2000 results.

 Good luck!  Nanda Srinivasan, Ed Christopher and I are trying to wrap 
 up our new Profile sheets using the 2005 ACS Place-of-Residence 
 tables, but we have had a lot of work on calculating Margins of Error 
 and incorporating the results into the tables.
