Any of you done it? Any tips?

I'm headed down to Destin the last week of this month. I'm always trying new things and this time I want to try fly fishing in the surf. My fly fishing skills are novice at best but I'm continuing to improve. I caught some nice bull reds last year surf fishing. That would be awesome, but I figured I could have my fly rod ready and when I see a ball of lady fish coming, I could just throw some sort of shiny fly at them. Sounded fun to me...what do ya think.
