The fish are always moving up and down the coast, but they encounter the most fishermen in LJ.

Good article and I agree with your viewpoint i.e. more anglers at LJ means more interaction between yt and anglers. there are yt boated by party boaters from SD up to marina del ray on a regular basis. YT just tends to be the most well known kayak spot likely due to access.
