Outdoor Wedding Columbus Ohio

All good ideas for an outdoor wedding in Ohio?
We are in the initial process of planning my wedding and looking for where the ideas for carry out the ceremony and reception. She wants an outdoor wedding in pleasant surroundings, with a reception indoors (preferably in place of the ceremony). We live in Mansfield, but are open to any area north of Columbus to Lake Erie. We would like a spring to establish if possible, but not a Dealbreaker. Anyone with ideas? Planning a wedding is semi-formal no more than 200 guests and would like to find a good value. The wedding will be at times in August 2009
Whetstone Park of Roses in Columbus is nice. I do not know if we could treat 200 people, however. Http: / / www.clintonville.com / parkrec / rosegarden.html
