Thanks guys.

I think I'll a least wear the hat in case it gets crazy and of course the glasses are a must. If it is wide open and/or people are lined up I can at least take the hat off.

Johnch the doves are not eating the olives in fact from what I can tell russian olives are not really an olive at all. I have heard they provide good roosting cover and the birds will head towards them. They tend to grow near water as well so I hope to pick up birds on the way in. They also allow an easy place to set up some decoys and provide a little shade and cover for the shooter.

My worry was that someone comes up from behind and starts blastin away with me on the other side of the bushes.
