I'm thinking about a trip to the surounding are of Las Vegas in Jan. Would like to see as much as possible in about four days, like Death Valley, Valley of Fire, Grand Canyon, Zion NP etc. Can anyone tell me what kind of temps to expect and the weather in general? What else should I put on my list within 200 mile radius of Vegas. Not interested in Vegas (BTDT) it's just a flyin point, and where I plan to rent a Wing. Thanks for any info.
