Call Phillips Electric. They sell only graded crawfish - #2's and #1's. The good thing about graded crawfish is that there are no wasted crawfish. They're all about the same size so they all cook the same. It's worth the extra money.
Call them during the week and order your crawfish for the weekend. Ricky Phillips is one of the wholesalers on Swamp People. He's been doing it for over 30 years. His brother's son sells them out of their electrical business located on Greenwell Springs road near Flannery.
