Welcome to the forum. I'm not too familiar with the northern part of the state, but down in New Orleans, there's a pretty good shop called Smokecignals. They've got several mods for sale, along with clearomziers, cartomizers, cases, pieces and parts, not to mention they mix
juice in the store to your preference. They'll let you walk in and try out flavors before you buy as well.
I got a flyer from them the other day advertising a vapor gathering at Finn McCool's on 3701 Banks Street in New Orleans on Thursday, June 20th at 7PM. They're going to have a couple local vendors (Cajun Vapes, Vape Me Chanix) as well as free food and giveaways. It says to RSVP on the New Orleans / Gulf Coast Area Vapers Facebook Group.
Enjoy your stay!
