I Want to Hike the Grand Canyon

I did a few years ago in late January. Started at the south rim, went down the North Kaibab trail to Phantom Ranch were I explored a few miles of the north side and then stayed overnight, and returned to the south rim on the Bright Angel. Luckily I was carrying crampons because it snowed heavily for the last three miles of the climb to the rim. Temperatures near the river are perfect in January: highs in the 70's F, lows in the 40s. I would love to do it again :)
