I haven't touched the fence sinced we moved into our house a few years back.  Needless to say, it's starting to show some wear and tear and finally one of the posts came loose.  I thought there would be a concrete anchor to the post but there isn't.  How should I go about repairing the fence?  I'm thinking of adding a concrete anchor and swapping out all the rotted and worn out wood and matching the wood pieces.  My wife thinks I should just hire a pro but I want to take a crack at it! :)
