Last couple of years I've gone to Welsh. They have a hybrid of the traditional chicken run, but its on floats that ride through the country. I didn't make it this year, but I heard it was muddy.
KBON has been advertising a bunch of really good bands playing in Eunice the weekend before Mardi Gras, but I feel like it will be packed.
One day I'd like to experience Mamou but I probably won't this year.
