I have seen small trailers setup to sell Crappie jigs at some of the Crappie Fishing Tournaments.

So maybe it might work if the price is right and the quality is what the fishermen want.

Remember what they say about business. 99% is Location, Location, Location.

Some tournaments have a after the tournament dinner and they sell a lot of stuff that way. People get together to eat and drink and talk. Lot's of friends are made and business conducted. People are in a better mood when they have good food to eat.
