I would tend to agree actually that digging a ditch on the beach together with the kids, seeing it fill with water, frantically trying to keep the walls from caving in and ultimately loosing to the incoming tide regardless is much more fun than digging a ditch in a swamp somewhere because $EMPLOYER likes swamp ditches. But swamp ditches pay the bills.

I will happily dig beach ditches for employers, no doubt, but only with adequate shade and breaks (don't work 80 hour weeks), drinks provided etc.
