Mohammed's site has excellent scoops and I consulted it before attempting the traverse last year. The Presi trails are a walk in the park compared to our lovely mudpit, root infested, cliff scaling, cripplebrush carnivorish paths of the Dacks. If you have the stamina and endurance, I doubt it will be a problem. However don't underestimate the weather. That was what turned us back after climbing Madison (in moderate winds and peekaboo sunshine) Adams (in 60 mph howlers with fifty foot visibilty) and then Jefferson (in zero visibility and the calm before the storm). Heading down toward Monticello Lawn the ravenous winds returned and brought with them horizontal rain. Hitting the Lawn, we debated our options (knowing thunderstorms were predicted for LATE afternoon... it was 11 am at this point) while the rain changed to some lovely biting hail. Hail meant the thunderstorms were closer than we hoped, and instead of going forward and bypassing Washington for Lakes, we headed back to Madison Hut. The lightning found us as we skirted the sides of Adams. Scary shit being up there as lightning slammed Adams and Madison in front of us, but scarier still was finding out Washington got hit a couple of times around the time we would have been arriving there had we buckled down and forged on. But, as far as the hiking, I was in great shape after doing the first three and the bulk of the climbing. If I don't make it back to do it this year, I'll get to it soon enough. Of course the day before when I arrived was one of those rare days when there wasn't a cloud in the sky and not a wisp of wind!
