Thanks for the tips: the Rock Creek prices are much more like what I was expecting. Reason for the resupply is that I plan to either yo-yo or more likely loop the HST (and I like to take my time) with a few days fishing and summiting around Lake South America and then back maybe by Pants Pass. Much as I'd like to pay my respects to the folks at the Portal, I want to bag Whitney and get the hell out of Dodge. Having been there last when I didn't need a reservation, water treatment or wag bag, I want to avoid the descent to the Portal (and the return climb) if I can. I think it would just break my heart. Might be an alternative, though, if am feeling up to the MR.
thanks again for the help
