I’ve sometimes wondered about getting a big plot of land, some cheap old heavy machinery, and letting people pay to play with it.

Probably liability insurance makes it impractical, which is a shame. There really is nothing like playing with a big excavator. Very fortunate that it was one of my formative experiences.

We've thrown some parties on the prop, and have often thought, "Maybe it'd be cool to let people try some of this stuff out," at which point we remember how incredibly dangerous something like an excavator is, even when closely monitored and in a safe environment, and then have nightmares about worst case scenarios. So, it's been a no-go thus far. What we have actually considered, though, is seeing about renting it out to a known-to-be safe / mature user to use on projects when we aren't. But, haven't pulled the trigger on that yet.
