Legistorm

You read about Legistorm's salary database here last November, and here's information about the travel database (if you've been wondering what those CODELS do - and buy - when they come to town, here's your chance to find out);
"Our travel database contains roughly 27,000 trips and provides a unique window into how private organizations are trying to gain influence in Washington. No other source of congressional trip data is as comprehensive or accurate or provides the users the same ability to view the original documents.

What's more, you can perform full searching, view each original disclosure form and check out maps of the trips. If that's not enough to keep you interested, we have identified which trips took place at a time and location coinciding with major events - like the Superbowl or Mardi Gras - which may have provided additional travel incentive.
