Are you thinking that next year might be the year you add some adventure to your life and hike or bike The Colorado Trail? If so, you may be interested in what people on the trail had to say about their experience. I interviewed over 100 backpackers and mountain bikers on the trail this year to see what they were thinking, doing, and experiencing on the trail. Their answers were funny, profound, and occasionally heartbreaking. See for yourself by reading Colorado Trail hiker interviews.

A problem with plotting wind vectors on map projections with cgDrawVectors was brought to my attention this weekend. Indeed, the vectors were pointing in the wrong direction. This was a tough nut to crack, but I believe the program works correctly now. http://www.idlcoyote.com/programs/cgdrawvectors.pro.

Everyone, including me, seems to be confused by the time or calendar data format. After looking into it this morning, I found it surprisingly easy to use. This article explains how to use it to read and write calendar data in a file.
