Howdy, Shadegardener, from a little closer to the lake. I have seen very very few JBs compared to other years. I think I've only seen 5 total. Like you, I just grab them and kill them. I never got around to using milky spore but the many moles in the yard do their best to kill the grubs.
They usually flock to my Kiss-me-over-TGG which reseeded little this year and is only now thinking about blooming, so maybe that's why I have so few? But I have a rose of sharon blooming and I think they love those.
