What would be some good flies to use on a casting egg? In the narrow river area?

I would try a Deceiver--Half/Half--Clouser any where from GS too the mouth off the river.Ocean side I would try a Bigger size off the same flies. Hope this helps.

On your other post,can you park a truck and trailer at the boat ramp or just at your house?

Just at my house, but my house is 1 block from the ramp.

Samll bucktails to big flatwings. All have worked for me.
