Funny how gravity is largely a function of time - Einstein's unpublished fifth law, or something like that. Three lbs weighs more than it used to. My nephew just sent me a family picture of them at Wanda Lk, largely still frozen. Now that his older son is 17, he wanted to replicate the trip I took him on that age over Lamark Col and up Goddard Divide, etc. In that instance, it was the third time I went up there hauling an 85lb pack with a Sinar in it, trying to get exciting light over the Enchanted Gorge. Tied ourselves to a ledge barely wide enough for the tripod itself, but finally got the light I wanted - color at sunset and B&W in the morning. Even though I was carrying 12 holders, those were the only two shots I took the entire trip, which next took the loop down beautiful McGee Can into Evolution Valley, then over the crest again (I have photographed those places on other trips). Gosh. Now I weigh backpack content like it was benzotriazole.
