I'm planning a North Rim Point-hop trip (leaving 7/13/14) and wondering whether you have any advice. I'm a serious photographer (www.skylineimages.com) and travel in a 2013 Tundra with 4WC. I've spent some time at Marble View and East rim, Dog, etc, and have shot fall color west of hwy 67, but never as far as the viewpoints. Thanks.
