I guided for 5 years.
If a client did not want to fish a waterway..we DIDN'T.

I always asked how many trout they averaged in the time out.
I asked them what their largest trout of the two prevalent speciesin the area were.My goals of the day were simple.
Catch their biggest brook trout and brown ever.Catch more than they had caught in time frame.
More times than not I turned them on to bigger and more fish.

I do NOT guide anymore.

Shop owner was very stand-up kinda guy to refund.
