Sharing too much information on social media can have adverse affects to your "secret spots."
It's no secret that using online resources can help us catch more fish, but the online game of 20 questions can be really annoying to the anglers who have put in the time and effort to understand the nuances of predicting the timing for a productive outing.
If you know someone who does this often, tell them to Please Stop Already, then send them over to Wide Open Spaces and tell them to watch this PSA.
Keeping secrets as a code of outdoor ethics is a tradition that is as old as time. It's a method of micro-managing your "secret spots" to keep people out of them that may not hold the same respect for the area, as well as maintaining low levels of competition for a shared resource.
Social media has greatly changed the speed of field reports, but by the time those reports reach people that are targeting those areas, the report itself could be irrelevant. Conditions change quickly, and fish, particularly migratory spawners like salmon and steelhead, move quickly from one area to another.
The only thing that remains constant in fishing is change. With that being said, there are droves of Internet anglers (and hunters too) that instead of using graphs, looking at the weather, and developing their own patterns through their personal experiences, simply want to cut to the chase of where there might be fish.
