I’m not sure if you’re refering Arizona LoCo’s activity. But if it’s right, I think you might want to have a look at this posting.
There could be many reasons for some LoCo teams prefer online over in-person. Like you know, In-person baisically require some input on finding some good place then making people show up at the place on the day.
As most LoCo leaders work with LoCo stuff on their free time after their main work, in case they are really busy with their own matter, they might prefer online over in-person. Or if the country or region that LoCo covers doesn’t have high density of population or the area is big, that could be reason behind difficulty to gather people in a place which could be another reason to prefer online.
