The point went completely past you.
I said no other LAND has a time period attached to it, and you jumped directly to the actual rides themselves.
Tell me what time period encompasses adventure. It has no time, which is why the rides in that land aren’t stuck in a specific period of time. The time period of Jungle Cruise doesn’t clash with the time period of Indiana Jones, which doesn’t clash with the time period of the Tiki Room, which doesn’t clash with the time period of Pirates, etc…. There is no time, it’s just adventure.
Tomorrow has no specific time. It can be any period that is beyond today.
Fantasy has no time.
New Orleans has no time.
Critter Country has no time.
Toontown has no time.
Main Street has no time.
World Bazaar has no time.
Western has no time.
Frontierland has a time. It’s from the 1600s to the 1900s. Which is exactly why a race car appearing in that land doesn’t make thematic sense. If it was just Westernland then Route 66 could go right past a saloon with no issue whatsoever.
