I live on the bay (salt water) and I am planning on building a fence. I was thinking of using redwood posts and redwood top rail. I was then going to use two horizontal stainless steel cables and run it through all 15 posts. The posts will be bolted to the bulkhead, so they should be very sturdy. My qustion is two fold, is redwood as good as cedar in this type of application? and do you know of any plans that cover this type of fence?
