some notes about the grand canyon.

people can hike, and quite a few do, from rim to rim. the distance for that is 26.9 miles. i would like to do that someday.
i started reading the book "the unpleasant profession of jonathon hoag" while i was there. i learned about california condors while i was there, and noticed that the cover of my book was graced with a california condor.
the california condor has a 9 foot wing span and stands just over 4 feet tall.
there is no such thing as a "down time" at the grand canyon, it is always full.
to stay at one of the hotels or lodges, you should make reservations 12 months in advance.
you can take mule tours down the bright angel trail, it is recommended to make reservations for them 13 months in advance.
if you would like to go whitewater rafting, you should make reservations 2 years in advance.
who does that kind of stuff?
