I think the meet-ups are a great tool for the littles ones to experience socialization with other Yorkies.
Unfortunatley, being waaaaayyyyy out East, it really wasn't convenient for us. And then in the Spring, they change the meet-up time to Wednesday at 6pm - which is even worse
I think you should def. go at least once and see for yourself. They are really a very friendly group, and I may try to start going again
