Excellent, Jim. There's always some neat goings-on at the BPL list. Don't forget to check their links to equipment deals.
Up till it finally failed in the storm atop Blizzard Gap in 2010, I've had great luck using a Gore-Tex semi-bivy (a 30 year-old Early Winters Pocket Hotel). Right at 1kg complete with stakes, storage sack, etc., it was as light as many tarps, erected even faster, and successfully weathered many a storm for me. Most of all, it took little space for ledge camping, as the photos show below:
(L) Nearly summited-out, Willamette Pass, Oregon Cascades
(M) Ledge camping in California's Warner Mountain Range
(R) Cross-country camping, Picture-Rock Pass, Central Oregon
(...all on 700x32C tires, by the way; can't wait to use the Sherpa's 26x2.0 Duremes in the same terrain...)
The replacement has a similar footprint, but with a detachable fly and mesh inner for bug-free warm nights and a small side vestibule that just allows the inclusion of all bags in the tent if desired, for just .5kg more. Best of all, I can actually sit up at the waist instead of just leaning on one elbow. The side-entry helps immensely in steady downpours and mud or snow. I remain really intrigued by the simplicity and versatility of tarps, but Ray Jardine hasn't quite won me over yet; to get bug protection and coverage against high winds, the modified tarps end up weighing as much as what I have, and with less convenience. Still, they are a viable alternative in most situations, largely without condensation, and generally can't be beat for low weight and pitching versatility.
Best,
Dan.
