I live at the foothills of the central California Sierra. This is premium hiking country. I have spent every summer on one kind of trek or another for the past seven years. I don't cache when I'm hiking because almost all my trips have been within either Kings Canyon or Sequoia National Parks. Next year (2005) I'm planning to do the Rae Lakes Loop. I have to do the more strenuous trips before I get old .... I'm only 63 now.
My most valuable piece of gear is my home made alcohol stove, followed by my Hennessey Hammock, topographical maps, compass, water filter and camp shoes, pretty much in that order.
