Yep, it is for non-members and members. I am not a member and have been there many times. The Eatery and sporting clays at elstonville are open to the public. You have to be a member to enter the bar.
If I am correct it is $10.00 for members and $12.00 for non-members. But dont hold me to it.
Mount Joy is also open to the public for trap, but you have to be a member to use the other facilities.
