In their long-running fight to prevent a New Orleans company from drilling a fracking oil well in St. Tammany Parish, activists have often pointed to other communities around the country as models for their fight.

One of those is Denton, Texas, where a grass-roots organization helped collect signatures to put a fracking ban before the city’s voters. That measure passed last fall.

Now, two of the architects of Denton’s anti-fracking movement are coming to Louisiana to meet with local activists and lead a symposium on how to replicate the Denton results in St. Tammany.

Adam and Amber Briggle, a husband-and-wife team at the center of Denton’s anti-fracking movement, will be the guests of honor at a celebration Friday night at the Pontchartrain Yacht Club.

The event — called “An Evening With Allies” — is sponsored by the group Tammany Together, a nonprofit, nonpartisan group whose website says it is dedicated to identifying important issues in St. Tammany Parish, educating members about those issues and exerting a “positive influence by speaking out with a unified voice.”

Tickets for the celebration are available for a suggested minimum donation of $15.

The Briggles also will lead a symposium Saturday afternoon in Covington. The symposium, titled “Victory in Denton — Can it Happen Here?,” will take place at the Covington City Council chambers from 1 p.m. to 4 p.m. Preregistration is encouraged. The event is being offered free of charge.
