My family has attended several of these events and we have had soooo much fun!
Check out https://www.facebook.com/FamilyFolkDancing. Logan has posted photos and videos from various dances. This is a very unique and REALLY REALLY FUN!
No prior dance knowledge necessary. Logan explains the steps in the beginning then off you go! One really funny quirk is that this is very well attended by guys. I have never seen a dance where the guys outnumber the girls. I think the way this dance is structured is what make it comfortable for everyone to dance, even those that did not come with a dance partner.
Also need to say that Logan chooses fun and whimsical music and is very much a showman. He puts a lot of energy into these events and clearly enjoys what he is doing. It is just fun to watch him out there being master of the dance!
