It's definitely growing in my part of the country. Thirty years ago, I had to go to Louisiana, or at least the southeast corner of Texas, to buy crawfish, but now I think all the larger grocery stores have the peeled and frozen tails. And while we had at least three "Cajun" restaurants open in the Dallas area, they all eventually closed; just didn't know how to fix real Cajun. But a few months ago, we found a restaurant chain in the area that really knows how to fix crawfish etoufee right!
And as for boiling them, not too bad, but certainly not good unless they're properly seasoned. You need lots of salt, chop up a few lemons and a few onions, and a couple of boxes of seafood boil. And if they're properly seasoned; no better eatin' anywhere.
