Point taken! The post ice age cave market was pretty brutal, but I heard from a friend of a friend that her friend was able to get a spacious, Oceanside grotto for only ten arrowheads and a sabretooth necklace! The only catch is that the previous owners were giant sloths. They left the place a mess.

Depends on the location. E.g. Would you like your cave on or off the Wooly Mammoth trail?

During or after the ice age?

Depends on whether it is furnished with cave paintings.

But shouldn't we try?
