Yes, it can be done! A beautiful fall day, and a circle of us standing in the fallen leaves while dogs ran on the left and workout mommies jogged with strollers on the right of us. We signed the license at a picnic table and took pictures by the gates. Remember, you can't officially BOOK a park like Trinity for a wedding - but if you're just having an impromptu celebration, with a handful of people (we had 8) you can usually just turn up and have a small, brief wedding. And hugs all around.
