Planning an anniversary trip for next March, and need advice. For star gazing, can anyone compare Joshua Tree and Catalina for me?? I'm thinking greater elevation at JT gives it an edge - but is it a BIG edge? If budget limits my trip, I may have to pick between the 2 and want to make an informed decision. ALSO - any concerns with JT and safety after dark or going out for viewing sunrise?? We plan to stay in Palm Springs, if that makes any difference. Thanks in advance!
