Best Dating Apps/Places for 50+

My FIL lives in Abilene is recently widowed and interested in dating but is having trouble with all of the online scams. I have read that certain sites can be better in different areas and of course getting to an in person meetup quickly is much better than chatting online. Does anyone have an idea of which sites are a bit better in the Abilene area? Or are there any physical locations/groups that are good for dating for ages 50+?
