AMEN indeed.
Yes, the DK folks provide fine cue sheets and a good rando would have used them. I kept them in my Camelback for backup. For me, it's far more effective to follow the breadcrumbs and virtual partner on a Garmin.
http://bikeroutetoaster.com/BRTWebUISince I only rode the half-pint (111 miles), battery life of the Garmin isn't a concern.
A co-worker loaned me their Edge 500. I used to own one, so I'm familiar with the unit. The screen on my cell phone was damaged a few week ago and slated to be repaired on my way out of town. That didn't happen because the replacement screen didn't fit. I intended to ride without a cell phone, but my fiance forced hers on me.
Jim Cummins and his staff do a wonderful job with this event. The ride was a blast, but my beloved Randi (IF naked Ti Club Racer) got trashed. I wish I had carried a camera instead of the cell phone. I saw infinitely more cows than cars, a dung beetle hard at work, a radar repeater tower at the "summit" of the ride with one antenna that appeared to have fallen to the ground, and lots of beautiful vistas. There was plenty of bounding, creek crossings, and wheel spinning on clay, but I was able to lay in the aerobars for much of the ride. I had no flats or mechanical issues, but saw a dropped chain in the first mile of asphalt, many flats, riders missing turns, a tandem with a trashed rear Velocity rim being walked back, and one pour soul on his back and face bloodied where ruts running along (parallel) to the track. One of my "teammates" passed out momentarily in a watering hole soon after the race. Funny, but not, a 200 finisher couldn't unclip after the line and managed to injure himself. They unclipped him, but couldn't get him off the bike. So they removed the saddle and post and rolled the bike away. He then managed to gingerly walk away.
