Here's a job ad that I pulled off of Monster (and did not apply to, needless to say, although if anyone out there is hiring, drop me a line!). It's a concrete company. And they require you to have a diver license. So...in addition to office work, does the job description include retrieving concrete shoes from the bottom of the river? ("Hey, Uncle Joey? Yeah, we've got a situation.") Maybe it's better not to ask.
