Criminy! It sounds like you read the whole blog. Thanks for your kind feedback.
Crotch joy can be addictive, still enjoying it at home. Also, I'd been averse to those boxers that cling to the thigh like bike shorts, but I became a convert on this trip and had zero chaffing.
No doubt, the JMT is a highway but so is the Annapurna Circuit in Nepal (of course, people live up there!) I'm of two minds. Happy to have done the JMT, but not likely to repeat knowing now the areas we'd like to return to for a solitary cross-country month.
Re: GPS batteries.
Five pairs of Lithium AA would do you for 30 days. Of course results vary with viewing/scrolling/backlighting but, I'd say I got 6+ days use for each pair (turning off the GPS only when we stopped for lunch or to make camp).
Re: geotagging photos. While I do have free tools to sync images and way points by timestamp, they're useless for a 30 day trek because (I learned the hard way) Garmin does not retain waypoint timestamps when you save a track on the device itself. And if you don't save, the older track points bump off into oblivion. I suppose I could've paid up for a larger microSD card to store the whole 30 days in tact.
Million thanks for taking time to check out: http://tzrecked.blogspot.com
