As a follow-up, my wife and I attended the Santee tailgate, organized by Angel (sklancha on the other forum). There were somewhere between 35 and 40 Teslas parked there and the Jacksonville news interviewed Angel, my wife, and niece, and a few other owners. The whole experience was an utter blast and it was great sharing it with other Tesla owners.
We are super charged about the whole eclipse experience and will travel for the next one, which begs the question: what Superchargers are in the path in 2024? Well, I counted 15 of them, and those are just the ones close to the center, with totality lasting at least 3 minutes. And that's today. By 2024, there may be a few more chargers.
