I've only played one of the two local courses, City Park, since Lafreniere is notoriously crowded with pedestrians if you don't get there in the morning, and mornings are tough for me. City Park has fared really well: no major trees on the course were uprooted. There was a lot of debris after Isaac, but the only major disruptions were the debris piles the park clean-up crew formed on two of the holes, one of which was pretty disruptive and sat there for weeks. Not sure why they couldn't find another spot to dump everything.
That aside, we were really fortunate: it was the city suburbs, especially those on the wrong side of the levees, which got hit the hardest.
Although the storms are of course a downside to living here, now that it's late October, I'm starting to realize how fortunate I am that I'll be able to play outside year round!
