Thanks to my parents scouting efforts we found some really great ceremony locations. We decided to go with a place that we could have both the ceremony and reception at, but I was really on the fence. Having a little time (more than just cocktails) for photos in between the ceremony and reception would have left us an option to go to a third location, but I'm happy with our choice.
An outdoor ceremony space I really loved was Taltree Arboretum. It's very well kept and has a lovely pavilion for cover, should you need it.
