I am a registered coonass and I can tell you New Orleans is not really authentic louisiana for many reasons. If it has any relation to food or culture in Louisiana we celebrate it and teach our kids the history of how we ended up here. Sorry about your kids, where did you relocate?
On another note I have several other large trees in my yard that have grass all the way to the trunk, some are oaks, cypress, pecan, and ash. I wonder why the grass is flourishing on them and not on the two in the front. I think the ones in the front are pin oaks at least that is what I call them, the kind that make several acorns but they are real small and the bark is real smooth. Its not the water oak (evangelline Oak) that are at LSU campus.
