So
1) I was at a Amelito Mirolo barn in UA for a wedding this past week, and it was great but HOT. So, if you're doing barn wedding, make sure you have some fans and some air circulation. (I know Amelito Barn has air conditioning, It just wasn't working very well.)
2) In other posts on this page, Lori from Westerville describes her beautiful barn.
HOWEVER - Lori's Barn is NOT available for rental (darn it!) Please read through some past posts, if you want to see the details.
If you do search barn or rustic on this board - which is quick and easy - you will find LOTS of great ideas for a rural feel wedding and reception.
