That would be sick. I met someone who began on the border of Mexico/San Diego and followed the Pacific Crest Trail all the way to Canada. The dude was from Squamish, Canada, and had prepared for this trip for a year. You have to go through the mohave desert, which will be challenging. Bring water, not just a purifier.

I am all for this... I hope you guys do it and have a great time. It should be awesome!
