From Jim Z. we have this email entitled, "I am a cautionary tale." It is good advice.
I know that you have been pushing PT for a long time in both of your blogs, and who knows, I may be the only one this stupid. After back surgery in January, I was finally able to start jogging again at the end of April/beginning of May, and to date, have made good progress, being able to jog 2-4 miles straight, with an additional 2-4 miles of walking. Today, I put my ALICE pack on for the first time in over a decade. I loaded it with about 20-30 lbs. After 3 miles, it had worn me out. Please try to drum it into people's heads that they won't be able to slap on 60+ lbs of gear (20 lbs if you just have a rifle, ammo, and water) and go easily, even if they have been jogging and exercising on a regular basis, if they haven't practiced carrying loads as well. Like I said, I may be the only one this stupid/arrogant enough to think that I could cover this distance easily, but somehow I think that there are others who are as dumb as I am.
On an unrelated subject, can you remind your readers to check the GM angles on their topographic maps and keep checking them every 6 months? The GM angle is shifting quickly and so most maps' GM angles are out of date.
Thanks again to both of you for having such useful sites.
