The Madisonville Gar Rodeo is back and bigger than ever as we celebrate 50 YEARS of this incredible tradition! 🐊🎉

Join us July 24–25, 2026 at Madisonville Park (Old Ballpark) for an unforgettable weekend filled with:
• Live music
• Jambalaya cook-off
• Kids zone & Pageants
• Vendors
• Mullet toss
• Bowfishing & gar rodeo divisions

Due to the ongoing construction for the Tchefuncte Breakwater Project and continued growth, we are excited to share that the rodeo will be moving to a larger space. The Madisonville Park gives us the opportunity to make our 50th anniversary celebration even bigger and better, and more family-friendly than ever before. Thank you to the Town of Madisonville for accommodating this year’s event.

This event would not be possible without the amazing support of our sponsors and community partners. We are incredibly grateful for everyone helping make this 50th anniversary celebration one to remember.

✨ Limited sponsorship opportunities are still available! ✨
If you’d like to showcase your business while supporting a great community event, now is the time to get involved.

𝗪𝗔𝗜𝗧 𝗨𝗡𝗧𝗜𝗟 𝗬𝗢𝗨 𝗛𝗜𝗥𝗘 𝗔 𝗖𝗛𝗘𝗔𝗣 𝗢𝗡𝗘!

In under 3 months we have replaced 2 engines in 2 separate trucks for this customer. Both engines were ruined in under 80k miles by poorly done mechanic work and tuning! Valvetrains damaged and scorned pistons.

All to often we hear about about “someone that does it cheaper!” Please pay attention to the work people are doing on your vehicles. If the cost is 𝗧𝗛𝗢𝗨𝗦𝗔𝗡𝗗𝗦 below other shops, I assure you, it’s not a quality repair.

This is extremely important in the 𝗧𝗨𝗡𝗜𝗡𝗚 world. There are LOTS of 𝗨𝗡𝗘𝗗𝗨𝗖𝗔𝗧𝗘𝗗 “mechanics” out there tuning trucks with cheap online bought box tunes with zero information on what they are installing. This can cost you 𝗧𝗛𝗢𝗨𝗦𝗔𝗡𝗗𝗦 of dollars.

Please come by or call us and we will gladly help you through the process with as much information as possible.
