This is more of a Green Day topic yet while exploring what Las Vegas has to offer (for client) in past 2 weeks, i noticed that Spring brings landscape watering restrictions to Las Vegas.
They are all spelled out by Las Vegas Valley Water District and are in effect until April 30, 2013 and in a number of videos.
You can water the lawn only on 3 assigned days per week.
No watering allowed on Sundays.
