You're right, there's no need to go at "rush hour." I hiked the Grandview trail first, then walked into the Back Country Office around three o'clock. No one was there so I picked up my permit (Nankoweap!) and was out the door in five minutes.
Yes, I could've faxed my request in, but where's the fun in that? This way not only did I cut to the front of the line, but I had a great day at the canyon... Us Married W/Children guys sometimes need silly excuses to get outside!
