I've had all positive experiences. Although, I have mainly gone to the Support group meetups like Social Anxiety. I've been to few regular meetups such as Art and film meetups. When I've gone , The Organizer will ask for $2 or $3 donation to cover monthly fee. Its better to have a group private so that the Organizer can eecide if the person is truly interested in group. There are weirdos out there.
