Thanks guys. I am going to do some more looking through google and other places to get some info on how to build it. If I decide to go with styrofoam where would be the best place to purchase it? I am thinking that I would like something say 12'x6' or something of that nature. I have alot to catch up on because I am wanting to try to fertilize a couple of the ponds and get my feeders fixed/running again. In all likelihood the dock will have to wait until after deer season this year. I have a great deal of work that I am wanting to do this summer.
