I was pretty nervous, as I'm no expert.
Nervous about the client getting skunked, about fishing my own flies, about seeming professional enough... the list goes on.
But, it went off without a hitch, dude caught 7 decent fish on a half day and we had a good time. Not lights out fishing, but pretty good for a cold day with a cold front moving in.
Looking forward to learning more and getting to do my 'dream job'!
