OK so a good friend of mine and I went to a local oxbow today and chased the carp, buffalo, and gar around on the fly and had a fair amount of success. We fished headstands for the carp and buffalo and did well when the sun was high and we could see them. The gar came up about the same time and became very agressive, we took them on white bunny leeches and gold variant leeches drug right in front of them thy would visciously slash at them.

This is a quick u-tube vid of one of the smaller gar of the day that we caught.
