Congratulations.
Solo is a big step. And you are right that it is a first step. Stay sharp. Know the rules cold. Follow the rules. Have fun.
California is a great place to fly, but also has many challenges. Mountains, traffic density, and rapidly changing weather can be deadly. I did one of my four real life missed approaches at Vandenberg when a fog bank came in and took the field below ILS minimums. At the now closed Mather AFB in Sacramento, I was cleared a left overhead and had to delay my break due to a 172 blazing through the pattern.
Pardon my running on. I miss the hangar talk.
Again, way to go.
