Spectators were kept about 3 miles from Saturn V launches, so you could build a REALLY WIDE stadium for Starship launches. The Circus Maximus wouldn't have ANYTHING on it.

We might be less than 50 years out from Starship or similar launches being as boring as a plane taking off or a train passing by.

I'm hoping it's more like 5 years to Starship launches being 'routine'. Maybe I'm an irredeemable optimist but that would at least be more similar to the curve of Falcon launches being 'routine' (I concede that to some of us, orbital launches will never be considered routine – no matter how frequent).

I'd even lay 50%-ish odds that they'll do back to back payload launches in 30 days or less by the end of next year. That'll of course depend on things going very well over the next few months so they manage to get a Starship to orbit and back on the ground at the launch site this year.

It will fly from Florida so that will be much easier then going to Starbase.

I saw an Atlas V launch at KSC in January 2017, from the LC-39 observation gantry, and it was incredible. Highly recommend seeing a launch – any launch! – if you have the means and opportunity.
