Ok, I am either going to be using a 6x8 post or telephone poles because I have them already. Those all sound like great ideas and I will let you know what I do when the time comes ( this week hopefully) anyways I have another question for you guys. I was wondering if I could use 1x6 or 1x8 oak lumber on the deck. From what I know oak is pretty strong and is already rot resistant I think ? The reason I ask is I can get about 100 of these for 150.00 dollars. I am looking to go cheap ,but still have something strong that will last. I am looking at a 16x20 to 25 foot dock. If I can use these how many inches apart should my joists be underneath which will be at least 2x6 if not 2x8. Please help soon because those materials may be gone soon. Thank you again, John
