Inexpensive Outdoor Reception Venue in Michigan - Lansing area?

I just recently got engaged and I am trying to get ideas for outdoor wedding reception venues. We don't have a budget set yet but are looking for something inexpensive since we are a fairly younger couple and have to pay for part of it on our own. We live in a town just west of Lansing, MI and are looking for venues anywhere around the Lansing area and surrounding. A tent would be a nice back-up in case of bad weather! Any serious suggestions would be extremely helpful! :)
