The Dallas/Fort Worth Coalition of Reason hosts an annual picnic for all member organizations (like the Dallas/Plano Atheists Meetup and Fellowship of Freethought) at Cedar Hill State Park each spring. This year it is being held on May 25th. We will be in the Group Picnic Pavilion J-1.
Camping is encouraged, though reservations must be made ahead of time (unless you make arrangements to share a site with other campers).
This event is potluck-style. So bring food for yourself and your family to enjoy. Many people do bring extra food and drink to share. And there are usually baked goods for sale.
There will be games and activities throughout the afternoon. If you are interested, bring along your fishing gear and/or a swimsuit. Don't forget the sunscreen and bug repellent.
