College students fucking LOVE blow-up bounce houses.
As a business investment, what is the long-term outlook for the bouncy house industry? I assume it has its ups and downs.
So far, it seems to be benefitting from recent inflation, but I wouldn’t want to be around when that bubble pops.
There have been downturns in the industry before, but it always seems to bounce back.
