Notifications of Raid Battles

I love this game. I play it everyday with my wife, but since did last update n started doing Legendary Raid Battles, not enough notification of when n where one going to happen unless you just happen to drive by n see one. Wish was way to get more advance notices before one happens so more ppl would be able to show up.
