I recently started a dads group in New York City (NYC) as a way to connect with other dads in a similar situation.  Our group has dads who are home full-time, part-time, freelance, and even a few working dads who take a day off once in a while to join us.  We are a divers group and welcome new members.  We are a small, but growing group of 63 dads.  About 12 of us meet weekly and take advantage of what the city has to offer during the week while most people are working!  We have a blog site as well to share some of our experiences and interesting content.  Our blog site is www.nycdadsgroup.com.  You can link to and join our meet up group from this site as well.
