The ADZPCTKO is awesome. Water reports, snow condition WAGs, trail angels, etc. Also, many who have thru-hiked in past years come and share their experience with the new class. I was amazed when I attended my first ADZ how much I learned, although I'd been backpacking for (insert big number here) years. More info will be at www.pct77.org/adz soon. See you there. AsABat
