all we need is here

so i've been busy lately trying to sort out this trip i'm taking with my oldest son next week. he's turning 13 and to celebrate we'll be motoring up to yosemite on the beem together and hiking half-dome. it promises to be a lot of fun and a little challenging.
one of the challenges will be packing only essential items for the trip. unlike in a car we won't have the luxury of bringing a bunch of stuff, and only later find it unnecessary. these bags will have to hold the majority of what we bring on our 3 day journey. and i like this constraint because it is forcing me to evaluate everything now very scrupulously and hold it up to the bright light of judgement.
in the end though it won't matter. what we have is all we'll have needed. the trip will conform itself to our resources. and whatever we think we lack we'll just have to pick up along the way...
