After trying a couple of times to do an epic Scamp trip to the great Utah national parks and register on the national parks site with endless frustration and disappointment, my wife and I have decided to head out to Utah and do the major parks west-to-east, i.e. Zion, Bryce, Canyonlands, Capitol Reef, Arches, and lots of other stuff in between, but not depending on getting rteservations for every night of the trip. We are allowing about a month to get there and back from the east coast (Philadelphia area). I actually succeeded in convincing my best friend and navigator that we would have more freedom and flexibility if we tried some dry camping options along the way, and get spots in private (or national) parks as needed. I was thrilled when she said, "Sure, let's try it."

But here's the question: It seems to me that, as long as we are prepared for some cold (possibly even freezing) weather, we can still do it in March. She's now talking more about April. My biggest deal-breaker is crowds. Any thoughts out there about Utah in March vs. April, and the crowds vs. weather tradeoff? Many thanks for whatever wisdom anybody can provide.
