From RonPaul2008.com:

Louisiana’s caucuses are scheduled for Tuesday, Jan 22 from 5:00 PM to 8:00 PM. Mark this date and time on your calendar and be prepared to attend, if necessary, ask for time off work. The following cities will host the caucuses: Shreveport, Natchitoches, Monroe, Alexandria, Lake Charles, Lafayette, Baton Rouge, Houma, Kenner, New Orleans and Covington. Voters will be assigned to caucus sites based on the parish where they are registered to vote. Fifteen delegates and fifteen alternates to the state convention will be elected from each congressional district. Republican voters are eligible to vote in the congressional district where they were registered on November 30, 2007. In order to participate, voters must present a driver’s license or valid photo I.D. If you or someone you know is interested in running for the position of delegate of alternate delegate please contact Louisiana Field Director, Andrew Axsom.

I cannot over-emphasize the importance of these caucuses. In Louisiana, the cacuses are all that matter. Ultimately, if Ron Paul wins on the local district level that translates into delegates voting for Ron Paul at the Republican National Convention. Louisiana’s delegate selection process is grassroots politics at its best. It means that “big money” is less important than “boots on the ground.” Please tell your family and friends to participate in the caucuses on Tuesday, Jan. 22 in order to win a major victory for liberty! The only requirement to vote in the Republican caucuses is that you were a registered republican before November 30th - and that you can prove it. The exact caucus locations are as follows:

More from Wikipedia:

On December 19, 2007, the Republican Party of Louisiana announced its procedures for selection of its delegates to the 2008 Republican National Convention.^[1]

The January 22 Louisiana caucuses select delegates to the state convention on February 16 in Baton Rouge. On January 22, 15 delegates and 15 alternates for each congressional district will be elected at the caucus sites by all registered Republicans in attendance. Participants are required to have been registered Republican by November 30, 2007 and present a photo identification for admittance. Voters will select up to 15 candidates on a secret ballot.^[2]

Twenty-one delegates to the 2008 RNC will essentially be selected by the caucus process, since these 15 congressional district delegates will then select three delegates and three alternates to the national convention. In addition, the state convention delegates, as a whole, will select 20 delegates and 20 alternates to the national convention as at-large delegates. Under state party rules, if there is a majority in the February 9 Louisiana primary, these 20 delegates are pledged to vote for the winner. Otherwise, these 20 will officially go to the convention uncommitted. Three delegates have already been committed to the Louisiana GOP chair and the two Louisiana representatives on the RNC (”party delegates”), and the other three delegates will be selected by the executive committee of the Louisiana Republican State Central Committee. ^[3]

Unlike other Republican caucuses, which feature a straw poll (or presidential preference election) prior to the election of delegates to the state convention, no preference election will be conducted. All delegates elected at the caucus are “uncommitted” and considered unallocated to any candidate. ^[4] However, many campaigns will distribute lists of delegates who will vote for their preferred presidential candidate. Delegates can be any Republican who has submitted the necessary paperwork and paid the $100 fee ($50 for alternate delegate)^[5] By setting up the caucus this way, it allows Louisiana to avoid the delegate penalties that have befallen Michigan, New Hampshire, and South Carolina.^[6]
