FYI
If there is a night launch and the sky is clear, the launch can be seen from Sebring and pretty much anywhere in the state. So if you do arrive in Florida earlier than the 11th just pay attention to the cloud cover.
But a day launch can be seen also.
I live in Miami and have witnessed at least 6 launches from my street.
Granted ... it ain't the best ...... but it can be seen from well over 100 miles away.
