I was standing mid-riffle and just upstream one started across, and when it noticed me it stopped swimming and the current carried him right into me.
I told myself to just freeze and remain cool but panicked at the last second because he looked like he was in position to strike.
I swatted at him with my rod (Stupid!) and attempted to high step away, slipped and fell, then recovered and ran to dry ground. Once I turned around the moccasin was nowhere to be found.
For a minute I wasn't sure if I had been bitten when I fell or not.
I'm not at all scared of snakes but that little episode kinda ruined my day.
