I plan to be in LA/San Diego during the first half of February 2013 and, as it will be the new moon period, would like to visit some dark-sky site for winter gazing. Currently, I am deciding between Joshua Tree National Park and Anza-Borrego Provincial Park. Of those two, which one you would recommend better? February seems to be the most cloudy period over there, so I don't know which area is on average has more clouds.
Thanks a lot!
