I don't know how it's been lately, but I went to the first preview last week, and you could have gotten on line at 1PM (when tickets are distributed) and gotten seats. There usually isn't much of a frenzy for tickets early in the run unless someone of Streep-like stature is involved. That said, I'd probably get there around 10 during the week and a little earlier for a weekend show.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
