I added the two separate Facebooks on here because the Facebook group contains information on meeting times that is not present on either their website (oops, I meant to add that before) or their Facebook profile, namely, the Alley Cat rides (e.g. https://www.facebook.com/events/418680934369640). 

I will move the mention of Alley Cat rides from opening_hours to service_times, as that is more appropriate for an event with a single beginning time. 

Is there a way I should indicate via tags the purposes for each of the separate Facebook pages? facebook:group, contact:facebook:group, or source:service_times perhaps? I choose to specifically use the profile for contact:facebook as that is where the operator communicates directly and where they accept messages, and I choose the group for facebook= because it seemed the only appropriate available key.
