Who is the audience for night meetings? To me it's families with working parents, which means young. As mentioned, older folks might have trouble driving at night. Where do young persons congregate? How do young persons get info? I'm thinking social media, children's sports events, colleges, trade colleges, laundramat, appartment buildings, child care facilities, exercise businesses, coffee shop, churchs. According to my daughter, the biggest, by far, is social media. I'd ask her (or the next generation) to send blasts to all her friends.
Another criteria is what time do you meet. Working persons need time to pick up the kids, drive home from work, feed the family, get to meeting. A 6:00pm meeting is too early, but too late for older generation.
Another thought, modern quilts appeal better than complicated traditional which takes too much time they don't have.
