My salt water club works one of the warm water ones. Not a whole lot of trout in South Jersey. We act as lake guides for the participants on the last day of the retreat. Each guide ties 14 flies, plus whatever ones club members who are not active participants tie up and contribute. The retreat this year isn't till early October, so I won't be tying any till later in the year. I'll tie an extra 14 when I get around to tying mine.
