As soon as there's a connector/bypass around that steep bit, I bet it does get split from Two Tickets to Upper Ticket and Lower Ticket.
For all the tiny trails at Blue, at least there aren't upper/lower pairs that can't have one part open without the other (IE Lower Main St can open without Upper, Nightmare doesn't have to be open to ski Dreamweaver, etc.). Shockingly, lower Lazy Mile could be a separate trail and isn't.
Personally, I'm in favour of Valhalla for "Paradise for badasses" but they obviously aren't taking suggestions.
