It looks like this was the designated meeting place for the Sunday service. The buggies were parked all around the farm, and the younger ones were by the barn playing. A typical Sunday for the Amish in our area as they alternate between different homes for church and a meal. You've never eaten a full meal until you had the pleasure of enjoying an Amish cooked chow down.
What a great farm, Rick! The National EMS Memorial Bike Ride rode through a PA Amish area a couple of years ago and stopped at a local fire station for a brief service due to a line of duty loss there - had to watch out for road apples :)
