Aren't you the one that took like 8 years to catch your first steelhead on the swing? I don't think the fish have too much to worry about with you over there.
Just kidding you man!
Not sure what to think about the seminar as I can see logic with both arguments. Lots of folks may attend who never plan on going over there and are just looking for an hour's worth of entertainment. Kind of like going to the Fly Fishing Show only saving $15 for the entrance fee. I wonder how many people won't fish the OP that weekend because they are getting their fishing fix from the free seminar rather than spending the $300 in gas, food, and lodging to go out to the OP instead?
Speaking of the Lynwood fly fishing show, I recall the last couple of years one of the guides who we did a custom raft frame for gave a packed-house presentation on the OP; it was SRO in the big auditorium. Does that mean we shouldn't have sold him a raft frame?
In all honestly, I am not convinced an hour-long Orvis seminar is going to make much difference in the overall abundance of wild steelhead on the OP. It might increase pressure a bit in the short term but that is probably about it. There are already too many other factors at play that are much more relevant.
