Navigationally speaking, things are totally different for me this year than last. Then, I went all crazy with pre-riding all the sections of the course, sometimes twice or more. And printing out all these high-detail sections on paper and marking them up with indelible ink in case I got caught in a monsoon. I tried a GPS app for my iphone, but the complexity of the task wore me down and the power requirements wore the battery down even worse, so I tossed in the towel on that and went old school.
Now, I have a Garmin (that I bought to save me from prematurely dying in the CDANF), to which I've added the perfect complement, which is Tom McFadden's cue sheet. Do yourself a huge favor and print a copy and stick it in your pocket. Tom does "quick training laps" of the MC course after work, and will probably go sub-6 hours this year, while still finding time to stop and make pine cone smiley faces in the road to amuse everyone he's smoking.
His cue sheet is dead-nuts accurate and filled with all kinds of helpful tips. Highly useful to those who know what they're doing and essential to the dopey types that show up thinking they can just "follow the pack".
Many will label me a major dork, I know, but I'm comforted by the fact that I have no doubt where I'm going. Thanks Garmin, thanks Tom.
