A few years back, I spent six weeks in Montgomery for work and a few colleagues of mine found out about a crawfish festival in the local area. It was pretty hick and in the middle of nowhere, but the beer was cheap and we got this bag full of crawfish for about 25 bucks.
It was more than enough for the eight of us. Simple way to eating them? Break them apart, suck the head (so to speak) and eat the tail.
And they were delicious.
