Falls Park in Pendleton has one of my very favorite gazebo's!  Pendleton is a small town in Madison county north of Fishers and south of Anderson.  It's a very affordable place if you are on a budget.  You can rent the gazebo for the wedding and the community room or the Red Barn for the reception.

​My fee to marry you in Pendleton is $150.
