If you are planning to fish the MRGO area, you would be much closer and have to cross much less open water if you launched in Hopedale vs. Delacroix. From Breton Sound Marina, you can take the spoil canal (runs parallel to the MRGO) until it ends and enter the MRGO there. If you are not familiar with the area, I wouldn't rely solely on the gps as there are many shallow flats and blind turns in the spoil canal. I know a few have posted a map with a safe route on this site, so you may try searching for those. Good luck!
