Mike,
Sorry to hear your fishin was so so. But fishing with friends trumps all .I have never fished the Grey Reef but have heard that if you're there when "they" are,it's a fly fishers paradise. We're still in Wyoming and ( NO LIE) fishing has been good. The Snake gave up several cuts and browns in the 16"+ range. We have been skunked on the Salt and Hoback Rivers but it was with friends so that didn't matter al all. A bad day (???) fishing can easily be tempered by friends, a great dinner and a few cocktails.
Tomorrow it's the Greys River and whatever happens, it's going to be great.
In any case, Mike, sounds like you don't regret the experience and will probably return.

Mark
