Don't go to the Terrebonne range, the range master is a dickhead an doesn't allow you to shoot "assault rifles"; even when I could I got harassed constantly by him even though I was respectful and followed the rules. I much prefer the Lafourche, much better people over there. The hours of operation last I knew were Wednesday-Sunday 8-5pm. Not sure about Sunday's hours though, I'd given them a call. $10 fee.
I've been to Lafourche a few times. Was just wondering about Terrebonne. I bought a new hunting rifle and need to sight it in before this weekend. They are both closed Mon and Tues.
