Wow, that's a lot of work you've got done! I rented a hydraulic one man post hole digger when I built since I knew an auger like you're using would break my arms! The pickets will go up fast with a nail gun. I screwed in about 7 of them before decided to pull out the compressor and nail gun...I don't know what I was thinking! Sorry you have such a grumpy neighbor. Glad you're on top of things legally, and I bet you can't wait to get that fence up! Are you planning to put up your pool after the fence it finished?
