Don't rule out your beach wedding ideas because you don't live near an ocean. The definition of a "beach" is - "the shore of a body of water." Yes, that includes lakes and rivers. For that matter, you could have a "beach" right by a swimming pool. There are no rules. Be creative!
It's your beach wedding ... it can be anything you want it to be — wherever you want it to be! Most of all ... have fun.
