Here’s a twist on the old gambler’s lament: When fate hands you lemons, make lemonade. The new one in Las Vegas can be: When your slot machine comes up lemons, make like a bulldozer!

The theme may also apply these days to Vegas construction companies. When the building boom slows down, invite tourists to pay to play with your bulldozers!

Instead of letting all that equipment sit around waiting for the economy to recover, builders have created another fun Las Vegas tourist activity. It’s called Dig This. Visitors can now try it along with the usual comedians, singers, dancers, helicopter rides to the Grand Canyon, ogling Boulder Dam and, of course gambling.
