Where to Fish This Weekend

I'm looking to take the girlfriend out for her first fishing trip this weekend and looking for some advice on where to go. I don't normally fish this time of year, so any input is welcome. The temp will be mid to upper 60's so more like spring than winter, but I wouldn't think the fish would fully transition into their spring patterns. I'm self-taught and still learning, so I could be wrong.

Areas I'm considering because I'm familiar with them:

1. The Rigolets/Lake St. Catherine - I could fish the main channel or intracoastal if they are still deep, bayous for medium depth or the lake itself if they are shallow.

2. Shell Beach - MRGO, Surge Gate, bayous, or lake?

3. Dam, bayous/marsh, or rocks?

4. Leeville/Grand Isle
