Following a vacation with Sara in Hawaii, I spent over a week in Nevada and Arizona. I was at an ASHRAE conference in Las Vegas, presenting 2 papers on energy efficiency. The first set of photos are at Red Rock Canyon - http://www.blm.gov/nv/st/en/fo/lvfo/blm_programs/blm_special_areas/red_rock_nca.html. I went trail running there twice between conference sessions, as this area is just outside of Las Vegas. There are a couple of Las Vegas shots, including photos of my BC Hydro colleague Toby Lau and his wife when we went to the Wynn for their famous buffet. Then I was off to Flagstaff, Arizona and the little town of Cameron on the Navajo Reserve. Following that, I went with my parents to Grand Canyon in the middle of winter, including the sites and some photos I took while running along the rim trail. The final photos are at the Hoover Dam near Las Vegas, the tallest concrete dam in the north america.
