That bulkhead was not special, nor any sort of hotspot. The truth is, you can pick any dock, pier, sod bank, bay beach, or bridge, and you’re likely to get covered up in snapper blues. The most important factor is depth. While the fish will feed on skinny flats, I’ve always found that areas with 4 to 10 feet of water produce best. In many cases, finding the right depth requires waiting for a high tide, but if your spot has 3 or 4 feet of water around it at dead low, you’ll catch fish.
