I belong to a few FB RV Groups. The founders of this group seemed to push it in a few. But have heard a few negatives, such as not enough people belong, or they don't update their location often and even they have nothing in common with those who are on.
We are okay with finding our own entertainment. If we want to discuss things to do, places to eat, we talk to the neighbors or someone in the RV Park office. It hasn't seemed to improved much since it first started and I looked into it.
