CAMPING WEDDING THEME??? Help!

Hi there! I`m hoping someone will be able to help and inspire me to plan the most unique wedding none of our guest will forget.
We were planning a wedding for July 2006, I have the gown, tuxes rented, flower girl dress, however on a trip to Vegas and a little too much tequila... We eloped. With ELVIS! ha ha.. (had to do it the right Sin City way)
Anyway.. We didn`t think it would be an issue with our friends and family. However as we came home, and tried to break the news to everyone with a very romantic, but yet very funny DVD of our ceremony... They were all a little bit hurt. So we decided to go on with our wedding plans for July, even though we already wed, so that our family and friends can bare witness to the union.
BUT... Since this is a unique situation, we want to make it as unique as possible. We live near a beautiful campground, which is easy to reserve with little notice. It`s got the prettiest spot on the river for a ceremony... However I have no idea how to pull all this together. Can anyone help me?
