Bass fishing, I think my longest zero streak is one day. Musky fishing though, I've gone a whole week long trip. Now that is demoralizing. In any case, I think one of the best things you can do is fish away from the crowds. Try and get out in the middle of the week. If that doesn't work you may want to take up golf for a few more weeks.
