Usually pretty warm in early October! Dress light but pack layers as the temperature drops when the sun goes down
You will be on grass and gravel most of Sunday. Wedges and chunky heels are better than stilettos.
This is really just an "after party", no big weekend plans. That said, we do aim to gather at Alta Plaza Park (north side) Saturday afternoon (around 2PM) to take in the air show for those who are around and looking to get together. For those staying in the Marina, walking > driving is ideal as we anticipate the neighborhood will be crowded and parking will be tough. BYO whatever you are in the mood to enjoy that afternoon!
