The US Interior Secretary and Director of the BLM toured the Imperial Sand Dunes at Glamis

story here: http://www.latimes.com/news/local/la-me-sand-dunes-20110221,0,4494274.story but in a nutshell they came to relate that motorized recreation fits into the Obama administration's "America's Great Outdoors " conservation initiative rolled out last week that is heavy on land preservation.
great photo by Allen Schaben, shows the secretary in a ranger's sand rail that got stuck when they went to go over a steep dune... nice new rail huh?
