I live in the Woodlands and we live for crawfish season. Unfortunately it's pretty much over, however there are a few hidden gems that may carry them. There is a Seafood Market attached to a restaurant called Crabby Daddy's on Rayford Rd, Bluewater Boil is a whole in the wall on FM 2920 but they have their own crawfish farmers that keep them in supply and I would also try Wolfie's. Good Luck!
