"Water event Lapras spawn patterns?"

#PokemonGO: While I was happy to see that this event has not been a repeat of the Valentine's event, with Porygon-empty biomes continuing to be Porygon-free, I've had no luck snagging a Lapras in this event. A couple of friends managed on the first day, but I've been frequenting those catch points to no avail. Trainers with better luck than I: are event Lapras more likely by water features? Do they show up at "rare spawn points?" Should I camp lures or buy some incense? I'm still playing several hours a day and would like to put it to the best use. via /r/TheSilphRoad http://ift.tt/2n6nKSx
