If you had all the space in the world

[Mikoh4792]

What sized enclosures would you give your snakes when fully grown? How much more space than the "minimal" size would you give them?

I got to thinking about what I would give my bigger rat snakes, carpet pythons...etc when they grew up. I've never seen a full grown carpet or russian ratsnake in person but I can't imagine a 4x2 would be ideal for a 6-8 ft snake, especially ones that like to climb and are more active than your ball python or boa constrictor.
