Is there enough water in the desert?

Sin City is growing...at a pretty fast pace!  Each time I go back to Las Vegas, I'm quite surprised at how far along construction has come along.  Big plots of land that were once nothing but dirt have been erected into 4 star luxury condo/hotels and condos.  These Las Vegas condos will be nothing short of spectacular.  However, it really didn't hit me until I was in my hotel room. 

I was in Vegas this weekend and I stayed at Harrah's.  After I shaved the 5 o'clock shadow, I reached for a towel and right under the towel was a little sign from the hotel that stated something along the lines of "If you do not put your towels on the floor, housekeeping will assume you will re-use them and not wash them.  We are trying to conserve our water supply so we don't wish to wash any towels unnecsessarily." 

It was such a subtle sign but at the same time it got me thinking about where Las Vegas is headed?  This oasis in the desert may one day in the near future have a serious crisis of limited water supply.  And the new condo development is certainly not helping the water supply.  What is going to happen?  No seriously...think about it.  There are over 25 projects in development just on www.newcondosonline.com.  We're going to have to face this sometime and we can't simply put this off.
